How to extend a EventDefinition ? [message #1650265]

Hi,

can anybody explain me how to extend a EventDefinition? What I want to achieve is a customEventDevinition similar to the CustomTask example. I want to use the 'TaskConfig' model extension to define my custom property tab also for my own custom EventDefinition.

The Example in the lunar branch (https://github.com/eclipse/bpmn2-modeler) seems to try something like that. But to me it looks as this example with the 'MyEventDefinition' did not work correctly. Beside the additional icon of the MyEventDefinition this element has no custom behavior.

The MyBounderEvent example is working with a custom property tab. But my question is if this is also possible for a EventDefinition which would better fit my needs for my usecase.

Thanks for any kind of help

I solved this problem. I decided to extend the IntermediateCatchEvent instead of the EventDefinition. This fits my needs perfect.
I understand that the EventDefinition is just a visual extension and not used to extend the properties of the event element.

The "MyEventDefinition" type specializes the BPMN2 "EventDefinition" and adds a String attribute called "value". This does indeed appear in the details panel "My Event Definition Details" when you add one of these to an Event:

Let me know if this isn't working for you...
