Hi,
I would like to extend bpmn 2.0 modeler by adding a new workflow pattern with the extended elements (Custom task: lane,pool,task...and the relationship between those elements ).
Can you help me?

Hi there,

I'm working on a tutorial that explains how to do this - should have something by today. I will post to this forum when it's available.

Cheers,
Bob

Hi, thanks you for your answers.
My question is :
How I can add an extended element (custom task) in the pattern workflow (object type) ?

Ah, my apologies. It looks like there are a few problems in the tool definition handlers. I have filed a bugzilla here:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=488792

Should have a fix in the next service release.

The problem is from the pool container and also from custom task?
Because I create a pool with a processRef =id of process and a Process+LaneSet+Lane but not working

Hi Jamila,

First, I'm sorry to tell you that this kind of nesting is broken with the current version of the editor, so please don't spend any more time trying to get it to work Confused

I am currently testing a fix for this problem and should have a new build by the end of this week, along with a working example.

Second, as you probably already know, in order for the editor to be able to distinguish a Custom Task from a plain BPMN2 Task, there MUST be some feature (either an extension attribute or element) in the task which your plugin defines. This feature must be set in the <tool> definition. For example the jBPM extension plugin defines a group of Custom Tasks that are identified by the extension attribute "taskName"; so the <tool> definition looks like this:

	<tool name="Email Task" description="This is a Custom Task that can be configured to send emails">
		<object type="Task[$taskName='Email']"/>
	</tool>

I don't want to go into too much technical detail, but when the editor constructs the task from this tool, it first asks all of the extension plugins if they recognize it as a Custom Task; if so, construction and initialization is routed through the extension plugin's Model Extension mechanism.

On another topic: I'm curious about how and why you are using the BPMN2 Modeler, and why it was chosen over some other solution? I'm trying to build a case to present to my product manager, arguing against discontinuing development of this project, and any support from the community will help my case.

Thanks!
Bob

Hi , thanks you very much for your answers
I defined a group of Custom Task that are identified by a extended attribute "type"
For example this :
<customTask
name="Communication Activity" featureContainer="org.eclipse.bpmn2.modeler.examples.comunicationFeatureContainer"
id="org.eclipse.bpmn2.modeler.examples.Communication Activity"
type="Task">
<property
name="type"
value="Communication Activity">
</property>
</customTask
And for the feature container
public class comunicationFeatureContainer extends CustomShapeFeatureContainer{

public comunicationFeatureContainer() {
}
private final static String TYPE_VALUE = "Communication Activity";
private final static String CUSTOM_TASK_ID = "org.eclipse.bpmn2.modeler.examples.Communication Activity";

@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;
}}
And for the Tool definition
<tool
name="communication">
<object
type="Task[$type='communication Activity']">
</object>
</tool>
But not working

I'm not sure what you mean by "not working"...is the task not showing up in the tool palette?

hi,

I have the same problem. I want to extend a pattern by adding an extended Custom Task ( exactly a participant). here is the code for more details:

<toolPalette
             id="org.bpmn2.modeler.toolpalette.my.full"
             profile="Full"
             runtimeId="org.eclipse.bpmn2.modeler.examples.customtask.runtime1">
			<category    id="category1"  name="category1"  >
				<tool   name="Pattern">
					<object type="Participant[$name='part1']" id="part1.id"  />
					<object type="Participant[$name='part2']" id="part2.id" />					
				</tool>
			</category>
	  </toolPalette>

i didn't know if there is a solution to resolve this problem.

thanks in advance
