hi;
I want to extend a Sequence Flow with an attribut when it links two event (that I defined).
In ather words I want the behaviour of Sequence Flow persist and I want to have a new connection shape in a sub palette.
is it possible?
thanks

hi;
because of the situation that doesn't allow me to create a new element in bpmn2 palette of type Sequence Flow I decided to not use the plugin extension and trying to explore the code of bpmn2 in order to add elements to the palette.
in my first step I added My metaclasses to the ecore file and I regenerated genmodel then .edit and .editor project.
in my second step I explored the grphiti plugin, so that I get bpmn2.ui and bpmn2.core and I added the code that correspond my metaclass.
as result, I was able to add an event and I sure that I can add any types of node but unfortunately, the problem of adding an element type connection persist.
so please do you have any advices for me. (lines of cod to add ...)
waiting for your response.
thanks

I will look into it as soon as I get the editor code stabilized for an upcoming release this Wednesday. Please have patience.
In the meantime, have a look at the <toolPalette> extension point, examples of which can be found in the jBPM plugin.xml

hi,
thanks for Pulling my attention to the jbpm project, and I remarked that we could have two shapes types association using an attribute to differentiate between them, so I tried to add a property and follow the same way and obviously it doesn't seems the best way, so that I spent a lot of time in figuring the code which is seems a bad idea either because each time I get an instable situation(non working shape for instance) , so I'm felling as a "man in whirlpool". Sad
so is there a way to introduce 2 shapes type sequence flow: the first one is the original and the second is extended using modelExtension.
I didn't want to disturb you but, I was facing a wall and I really need your help.
thanks a lot. Smile

Hi Mhammad,

I've been working on this and after some code refactoring, it's now possible to create custom connections as well as shapes. I need to do some more testing, but so far it looks pretty good. I should have something for you to test out by tomorrow.

Cheers,
Bob

OK, give it a try. You'll need to refresh your git repository from here: https://git.eclipse.org/c/bpmn2-modeler/org.eclipse.bpmn2-modeler.git/
The latest Kepler build with these changes is here: http://download.eclipse.org/bpmn2-modeler/updates/nightly/kepler/

Have you looked at the SampleCustomSequenceFlowFeatureContainer class? Is this not what you were asking for? I don't know what else to do to help you.

Hi Robert;
I tried to figure out the problem, so I compared MyEventDefinitioFeatureContainer with other FeatureContainer to much the methods that could help.
Effectively, this implementation allow me to resolve the "canAdd" Problem of MyEventDefinition
Quote:


public boolean canCreate(ICreateContext context) {


Event e = (Event) getBusinessObjectForPictogramElement(context.getTargetContainer());
if (e instanceof BoundaryEvent) {
return true;
}

return false;
}



thanks to this method the symbol "not allowed" has been disappeared(the super implementation return false), but unfortunately MyEventDefinition couldn't be added. Confused

I hope that this could help us.
Thanks

Hi,
when I read about the plugin extension I deduced that we could extend the bpmn2.0 metamodel using an ecore file, indeed, The demands of my work oblige me to have a new meta-classes that extend from defined meta-classes (event Definition and sequence flow).
the super imlementation of canCreate() return true only if the element invoked is type of BaseElement, in the custom task example I remarked that you didn't define any meta-class, and I saw that this could be the problem of not having a BaseElement type.
In my case I defined MyEventDefinition (extends EventDefinition), and as it mentioned in my previous comment, I'm permitted to add MyEventDefinition and effectevly, it is shown on the xml file, but it doesn't figure on the graphic.
I tried to solve this graphic problem by redefining the addFeature, but unfortunately I didn't get the wanted result.
so please could you take a look and tell me what should I do.
waiting for your help.
thanks

Hi Mhammad,

I've updated the customtask example and fixed the EventDefinition extension. The problem was that enablement of EventDefinitions was controlled by a complex set of rules (enforced by the BPMN 2.0 spec) in the base class and the MyEventDefinition did not match any of those rules.

hi Robert,
looks there is something broken;
obviously the rules managed to activate the event definition are not fixed to elements of other type. Confused

hi Robert;
I'm so grateful for every thing you did until now, but could you help me one last time. Embarrassed
you have commented above the SampleCustomSequenceFlowFeatureContainer class situated under org.eclipse.bpmn2.modeler.runtime.example bundle
Quote:

/**
* Example implementation of a Custom Connection feature container. The main things to consider
* here are:
*
* createFeatureContainer() - creates the Feature Container that is responsible for
* building the "custom connection". This can be a subclass of an existing Feature Container
* from the editor core, or a new one. Typically, this should be a subclass of the
* Feature Container for the type of bpmn2 element defined in the "type" attribute
* of this Custom Task extension point.
*
* If your Feature Container extends one of the existing classes from editor core, you should
* override the following methods:
*
* getAddFeature() - this should override the Add Feature from the chosen Feature Container
* base class (see above). Typically you will want to override the decorateShape() method
* which allows you to customize the graphical representation of this Custom Connection figure.
* getCreateFeature() - this MUST be overridden if you intend to add extension attributes to
* your business object (bpmn2 element) - see the code example below. You will also want to
* provide your own images for the tool palette by overriding getCreateImageId() and
* getCreateLargeImageId() in your Create Feature.
*

I'm trying to elaborate a new one, so I spent all this period to do it and unfortunately I couldn't get it. Sad
I wanna note that I want to create a new custom connection named dependency and it should be written in the xml file like this:
<dependency sourceref="xx" targetref="yy" property="zz">
thank you very very much Smile

ok, so it looks like <dependency> is an extension element, which means you have to create an extension model. The CustomTask screencast shows how to do that.
So, I have a couple of questions:

1. should Dependency have any of the attributes of any of the existing BPMN2 connection elements (i.e. SequenceFlow, Association, etc.) If so, you can define your Dependency element as a subclass of an existing BPMN2 element.
2. what will be the container for your Dependency elements? For example, SequenceFlows are contained in a FlowElementsContainer (more precisely, one of its subclasses like Process or SubProcess or Choreography). If Dependency will be treated similarly, then it MUST subclass a BPMN2 element (in this example, it must be a FlowElement if it's going to be contained in a FlowElementsContainer).
3. can Dependency be treated like an extension element? That is, can its containment look something like this:

  <bpmn2:process ...>
    <bpmn2:extensionElements>
      <tns:dependency sourceref="xx" targetref="yy" property="zz"/>
    </bpmn2:extensionElements>


if it cannot be contained like one of the existing BPMN2 elements, then it needs to go in the <bpmn2:extensionElements> container.


Also keep in mind that your extension element will belong to a different namespace (in the example above "tns" will be the namespace of your EMF model).
Lastly, Dependency should have an "id" attribute if it will be referenced by other elements in your model. At the very least it should subclass the BPMN2 BaseElement.

Cheers,
Bob

hi Robert,
my extension target to add 2 elements which are subtype of eventDefinition and a connection whose name "Dependency" that links these 2 elements.
this connection hasn't any relation with any other bpmn2 connection (i.e. SequenceFlow, Association, etc.), it is a FlowNode.
the problem is to create a featureContainer specific to my Dependency customTask.
waiting for your response
thanks. Smile

ok, I'm confused...if it's a FlowNode then your feature container should extend CustomShapeFeatureContainer, but if it has the properties of a connection line (it can't be a FlowNode, a FlowElement maybe?) then you should extend CustomConnectionFeatureContainer. Which one is it?

I've never actually tried to build a custom feature container for an object type that doesn't extend one of the BPMN2 types. I'll take a look to see if it's possible...

hi Robert,
sorry for the mistake, I meant to say FlowElement.
so please could you please if it is possible to create a custom connection that extend CustomConnectionFeatureContainer other than SequenceFlow and Association.
thank you very much.

Hi Robert,
the SampleCustomSequenceFlowFeatureContainer class situated under org.eclipse.bpmn2.modeler.runtime.example bundle aims to create a sequence flow named Mitigation Flow.
Quote:

public class SampleCustomSequenceFlowFeatureContainer extends CustomConnectionFeatureContainer {

@Override
protected IFeatureContainer createFeatureContainer(IFeatureProvider fp) {
return new SequenceFlowFeatureContainer()
{

@Override
public IAddFeature getAddFeature(IFeatureProvider fp) {
return new AddSequenceFlowFeature(fp) {

/* (non-Javadoc)
* @see org.eclipse.bpmn2.modeler.ui.features.flow.SequenceFlowFeatureContainer.AddSequenceFlowFeature#decorateConnection(org.eclipse.graphiti.features.context.IAddConnectionContext, org.eclipse.graphiti.mm.pictograms.Connection, org.eclipse.bpmn2.SequenceFlow)
*
* This implementation of SequenceFlow's decorateConnection() changes the appearance of the connection
* to distinguish it from regular SequenceFlows.
*/
@Override
protected void decorateConnection(IAddConnectionContext context, Connection connection,
SequenceFlow businessObject) {
super.decorateConnection(context, connection, businessObject);
connection.getGraphicsAlgorithm().setLineWidth(3);
connection.getGraphicsAlgorithm().setLineStyle(LineStyle.DASH);
}

};
}

@Override
public ICreateConnectionFeature getCreateConnectionFeature(IFeatureProvider fp) {
return new CreateSequenceFlowFeature(fp) {

@Override
public SequenceFlow createBusinessObject(ICreateConnectionContext context) {
SequenceFlow businessObject = super.createBusinessObject(context);
return businessObject;
}

@Override
public String getCreateImageId() {
return SampleImageProvider.getImageId(customTaskDescriptor, IconSize.SMALL);
}

@Override
public String getCreateLargeImageId() {
return SampleImageProvider.getImageId(customTaskDescriptor, IconSize.LARGE);
}
};
}
};
}


the methods getCreateConnectionFeature and getAddFeature define the nature of the connection which is in the particular example above is a SquenceFlow.
is it possible to create an equivalent to SquenceFlow named "Dependency" which is a FlowElement defined in myEcore in order to get this kind of tag in the xml file:
<Dependency sourceref="xx" targetref="yy" property="zz">
it doesn't matter if it came as like as this form:
<bpmn2:process ...>
<bpmn2:extensionElements>
<tns:dependency sourceref="xx" targetref="yy" property="zz"/>
</bpmn2:extensionElements>

I tried to reform my request and I hope that you get me.
thank you very very much
your are the best. Smile

hi Robert,
I tried to give a shot, so this is the description of the steps that I made and I hope that you give your opinion about it.
I created a class named TemporalDepedency->FlowElement in my Ecore.
TemporalDepedency has 3 attribute:
-sourceRef which reference a BoundaryEvent
-targetRef which reference a BoundaryEvent
-lagTime type EString
in runtime extension point I defined TemporalDepedency as the following
Quote:

<customTask
category="Time-BPMN"
description="TemporalDependency"
featureContainer="org.eclipse.bpmn2.modeler.examples.timebpmn.TemporalDependencyFeatureContainer"
icon="TemporalDepedency.png"

type="FlowElement">
<property
name="lagTime"
type="EString"
value="3hr">
</property>
</customTask>


I defined TemporalDependencyFeatureContainer class like this
Quote:


public class TemporalDependencyFeatureContainer extends CustomShapeFeatureContainer {

private final static String TYPE_VALUE = "TemporalDependency";
private final static String CUSTOM_TASK_ID = "org.eclipse.bpmn2.modeler.examples.timebpmn.temporalDependency";

public TemporalDependencyFeatureContainer() {
}

@Override
public String getId(EObject object) {
EStructuralFeature f = ModelUtil.getAnyAttribute(object, "type");
if (f!=null) {
Object id = object.eGet(f);
if (TYPE_VALUE.equals(id))
return CUSTOM_TASK_ID;
}

return null;
}


@Override
protected IFeatureContainer createFeatureContainer(IFeatureProvider fp) {
return new TemporalDependencyFeature()
{

@Override
public IAddFeature getAddFeature(IFeatureProvider fp) {
return new AddTemporalDependencyFeature(fp);
}

@Override
public ICreateConnectionFeature getCreateConnectionFeature(IFeatureProvider fp) {
return new CreateTemporalDependencyFeature(fp) ;

}
};
}
}

if you have remarked, I create a class named TemporalDependencyFeature (I followed the SequenceFlowFeatureContainer).
despite this, it still doesn't work.
waiting for your response. Smile
I hope I'm not bothering you Embarrassed
thank you very much. Smile

Hi Mhammad,

It turns out that what you're trying to do was not possible previously Embarrassed

I have created this bugzilla to track the issue and am working on a fix for this. It should be available in tonight's build. Please check the nightly build update site.

I've also enhanced the custom task example plug-in to include your use-case. Please pull down the latest source code from git to see how this is all done.

Thanks for helping to improve the extension API Smile

Bob

hi Robert;
I have two request,
I tried a several time to add a property tab that I can update lagTime through it, so please is there an example that could help. Rolling Eyes
I also wonder if it is possible to show the value of lag time as a decoration in the center of Temporaldependency between "[]" : ----------[]---------->
thanks for your help. Smile

Hi Mhammad,

Sorry for the late reply. I finally got around to trying this out myself and discovered that there's a bug which prevents the definition of <propertyTab> extensions which involve classes not defined in the bpmn2 metamodel. See Bug 425047 for a description.

I've also enhanced the org.eclipse.bpmn2.modeler.examples.customtask example plugin to demonstrate how to define a property tab for these custom objects.

Cheers,
Bob

hi Robert;
you've done an excellent job.
could you tell me if it is possible to show the value of lag time as a decoration in the center of Temporaldependency between "[]" : ----------[]---------->
I also wonder about the possibility of showing the proprety of MyEventDefinition on top of the shape on the diagram.
thanks

hi,
in the customTask example and exactly in the configuration of TemporalDependency, I remarque that the "runtime id" is defined as the following "org.eclipse.bpmn2.modeler.examples.timebpmn.runtime" which does not correspond the runtime id of the plugin which is "org.eclipse.bpmn2.modeler.examples.customtask.runtime".
could you explain this dis coordination please.
thanks a lot.
