extending the palette [message #1066008]

hi;
I'm student in sfax university sfax, Tunisia.
I was looking for an open sourse bpmn editor to implement our research ad I'm interested to yours.
I want to extend the palette of bpmn2 with special type of boundary event(catch and throw event) beside a special type of connection.
I saw the tutoriel of the costoum task extension and I was motivated to use this plugin because there is a note says that the extension is allowed for all base element.
so what should I do to implement my shapes.

thank you. Razz

Hi Mhammad,

Try following the tutorial video, but substitute all references to Association with BoundaryEvent. That should get you started. Let me know if you run into problems.

I'm guessing the errors are because of unresolved dependencies. Try installing all of the editor features into your eclipse development workbench from the nightly update site - this will install all of the dependencies you'll need to build and run the product. Then simply import all of the plugin source into your development workbench and you should be able to launch the editor. If you use EGit, you can clone the git repository and have it available in your eclipse workbench - do the "Import existing projects" from the EGit repository browser to get all of the plugin projects.

The plugin from the video is in the "examples" directory and is called org.eclipse.bpmn2.modeler.examples.customtask.

HTH,
Bob

Can you give me some more details about exactly WHAT is not going well? Are there still missing dependencies? Compile errors? Runtime errors?

hi;
frist of all I want to note that the metamodel project does not seems like the one in the tutorial: there are a sevral project (edit, editor, feature ...) not one project like in the tutorial.
the errors are shown in 4 projects:
org.eclipse.bpmn2.modeler.core
org.eclipse.bpmn2.modeler.runtime.example
org.eclipse.bpmn2.modeler.runtime.jboss.jbpm5
org.eclipse.bpmn2.modeler.ui
and there are a Compile errors.
I doubt that it is a compatibility problem, in other words, I think that the update site used does not match with the cloned projects.
so please could you give me a link approved to deal with the extension.
thank you for your generosity.

If you look on the eclipse project home page here: http://eclipse.org/bpmn2-modeler/
you'll see a section called "Download" - click on that. Try the nightly builds because they are most up-to-date with the source code.

Which version of eclipse are you using? Make sure you install the editor for your version because there are two available:

For eclipse indigo (3.7) and juno (4.2), use the http://download.eclipse.org/bpmn2-modeler/updates/nightly/juno/ update site;
for eclipse kepler (4.3), use the http://download.eclipse.org/bpmn2-modeler/updates/nightly/kepler/ site.

Other than that, I don't know what kinds of errors you are seeing because you haven't posted any useful information here.

hi,
the tutorial was exellent and
understandable, but as you know I'm creating a "boundary event" not a "Task".
so, I tried to change "graphiti feature container" to class that extend org.eclipse.bpmn2.modeler.ui.features.event.BoundaryEventFeatureContainer
but unfortunatly it doesn't work. Mad

before that, I made my own ecore file for extension with a documentroot which has 2 reference to two object:"my boundaryevent" and "my connection", each one of them has a property name, I had enabled just one object ("my boundaryevent") and I arranged its property but I had the properties of the old example "custom task" instead of them. Shocked

please, could help me to get it as soon as possible Embarrassed

I'm waiting for your reply. Rolling Eyes

thanks

Have you tried replacing all references to Task with BoundaryEvent in your plugin.xml?

Indeed, I tried to replace all references to Task with BoundaryEvent except FeatureContainer because I' not permitted to change it which is the main problem until this stage

hi,
I didn't want to disturb you but I just want to note that I couldn't have child to org.eclipse.bpmn2.modeler.runtime type base element bpmn2 other than custom task.
so I wonder how could I have a child which its type is boundary event or connection.
please, sent me a response as soon as possible because we are chased by time.
thank you very much

Hi Mhammad,

I've updated the custom tasks example to illustrate how to extend a Boundary Event. This also pointed out a minor bug, which has been fixed along the way Wink

These changes will be available in tonight's build, or you can pull down the latest source code from the eclipse git repo.

Have fun!

hi;
the boundary event needs to get an event definition (timer, error, message...), indeed if you restart the execution you 'll have this error "Catch Event has no event definitions" Sad

; so could I create my own event definition and effect it to the new boundary event. Rolling Eyes

secondly, I wonder if it is possible to create a special type of connection. Confused

thank you very much. Smile

I have extended the customtask example to include event definitions. Check the git commit record to see what was changed.
The other example plugin (org.eclipse.bpmn2.modeler.runtime.example) extends the Association (a connection) element - this should get you started.

You're welcome. We are still working on finalizing the extension API, so your feedback and use-cases are always welcome and will help us improve the API Smile

hi;
in case I secceded to implement my extention I wonder if it is possible to execute the workflow on JBoss whitout problem.

the example of extension of the association doesn't work perfectly

thanks.

It all depends on if jBPM "understands" your extensions. If it does not, then there will likely be problems.

hi;
I want to have a boundary event like the others, ie I want a shape that contain an event like the default boundary in bpmn2 palette.

could you see the example of extension of association because I think it doesn't work.

my third request is about jBPM:
I think that jBPM doesn't "understands" the event which I'm adding them because it works on different logic, so I have to adapt jBPM on my extension, am I right? Rolling Eyes

hi;
I want to have a boundary event like the others, ie I want a shape that contain an event like the default boundary in bpmn2 palette, moreover, I get these 2 errors

( The hierarchy of the type MyBoundaryEventDetailComposite is inconsistent)
and
(The hierarchy of the type MyBoundaryEventPropertySection is inconsistent)
so, I read about this error and it seems that it is a problem of a missing jar and I think it's not, or, it is due to a deficiency in our extends/implements tree which I found it odd, because I copied it from your customtask example.

could you see the example of extension of association because I think it doesn't work.

my third request is about jBPM:
I think that jBPM doesn't "understands" the event which I'm adding them because it works on different logic, so I have to adapt jBPM on my extension, am I right?
beside, how jBPM does behave when it get <extension> tag.

Hmm, it's possible that you are missing a plugin in your development workbench, but I doubt it. Make sure that you import all of the BPMN2 Modeler and BPMN2 metamodel plugins into your workspace before trying to compile the CustomTask example - that's probably where your missing dependencies are Wink

As far as jBPM runtime is concerned, the answer is "yes", you will have to modify the jBPM engine for your extensions, but be warned: this is not a trivial task and probably not something you can accomplish on a rainy weekend.

HTH,
Bob

hi Robert;
I solved the problem of the missing dependencies by working on the"customtask" project but, the problem facing me now is how to create a sequence flow?
I saw the example of extention named "Sample Business Process Engine" in the bundle org.eclipse.bpmn2.modeler.runtime.example and I think it doesn't work very well, so could you verify it. Rolling Eyes

my second question is about the XML file resulting my plugin extention, I wonder what is the class charged to tagged my event in the XML, I'm asking because my events are tagged differently than I named. Confused

I hope I'm not disturbing you Embarrassed

thanks alot. Smile

hi;
sorry for the stupid comment because when you told me that there is an example of an extension of an association I thought that I will have an icon in a sub palette like other custom tasks, so it was a misunderstanding. Embarrassed

on the occasion of that, is there any way to have my spcilazed sequence flow in a sub palette.

how could I make a property of my custom task visible on the diagram(like a task name) and it's better be beside the shape.

could you please reply me soon because it's so important Confused

thanks
