Customization of BPMN TASK

PostPosted: Tue Nov 22, 2022 7:35 am

I have create a customization of BPMN task activities and everything is working fine.
But if i add my customization to the diagram panel and try to use it, i have the following error message : "Element of the defined metaclass cannot be created".

I understand that the metaclass "Action" is a abstract element and therefore i can't use it (this is stated in the UML specification).

But the metaclass of the native BPMN task activities is also "Action" and we can create Task in a BPMN Process Diagram.

Am i doing something wrong?
I really want to use my customization directly from the diagram panel and not create a Task and use refactoring.

thanks in advance :)
