Hi all,
I'm new to the bpmn modeler, and i've got some question.
I need to extend the bpmn modeler to support custom "Annotation".
I've followed the tutorial videos provided by the docuemntation page of the bpmn2.0 modeler site. The video explain how is possible to add custom task.
I tryed to replicate it adpating to my needs, but unfortunately i couldn't get it work.
The extension point "org.eclipse.bpmn2.modeleler.runtime" has a specific "customTask" subnode, and i couldn't add my custom "Annotation".
I've also looked at the modeler.runtime.example plugin but it hasn't help me much more.

How I can achieve my objective? Can someone help me?

Tanks in advance
Mauro.

Hi Mauro,

The <customTask> extension is somewhat of a misnomer, because you can actually use it to extend any BPMN2 model element that subclasses BaseElement. All you need to do is change the "type" attribute to something like type="TextAnnotation". I have a working example that does exactly this and even changes the Text Annotation graphic from its default "[" to something that looks like a Task with custom image decorators. I will try to add this to the examples branch in the Git repository, when I get back from vacation next week.

Cheers!
Bob

Really thanks bob!
I'll wait for your example!
Can you notify me when you've uploaded the example?

Tanks again!
Mauro.

Hi Mauro,

Just realized the example I was thinking of is already available in the org.eclipse.bpmn2.modeler.runtime.example plugin. Have a look at the plugin.xml in that project - you'll see that the <customTask> extension does specify type="TextAnnotation".

Let me know if you need help!
Bob

Hi bob, sorry for the late reply.
I've looked the example you pointed me.
After some try i've finally extended the TexeAnnotaton, also with a custom model and custom property.
Now, i've got some other questions for you Smile

.
* The extension "property tab" of the "org.eclipse.bpmn2.modeler.runtime" ep permit to substitute an existent tab.
My qestion is how I remove a default tab (without substituting) (e.g. the "Text Annotation" tab)?
I've also tried to fill the "propertyTabs" field of the "Custom Task" with the tabs id, but nothing change.
* Another thing: Is possible to extend the Association link with the "custom task" extension (As the text Annotation)
and have a new tool in the palette with a custom "createFeature"?

* I don't know if this is a bug or not, but i can see my "CustomTextAnnotation" (element and palette tool) only on
process diagram. if i try to open a collaboration diagram or a coreography, my tool are not created. There is something to configure?
* Last question: there is a way to set a "modelEnablemnet" as default profile, without the need to go in the preference and ovveride the default profile?

Sorry again for all this questions...

Really Tanks in advance!

Wow, almost a month and I haven't replied to your question yet - shame on me! Wink

In general, to disable a property tab, the Property Section's appliesTo(IWorkbenchPart,ISelection) method should return "false". You can do this by overriding the default property section and providing your own appliesTo().

HTH,
Bob

Hi everybody,
please i don't find the project that has a working example that extends text annotation and changes its graphic from its default "[" to something that looks like a Task with custom image decorators . Does it still available? Please, can you provide the link?
Thanks

Hi,
you can find a lot of tutorials here:
https://wiki.eclipse.org/BPMN2-Modeler/DeveloperTutorials
But as Bob explained, the extension mechanism is not restricted to the CustomTask. You can extend any element.
This may be what you are searching for:
https://wiki.eclipse.org/BPMN2-Modeler/DeveloperTutorials/CreateCustomShape

See also the CustomLayoutAdapter :
