I didnt have much time in the past but want to continue with my project now. Robert got me started with his help, thanks again for that! I looked up the jbpm target runtime extension. Now there are some things I dont understand yet. I loaded the source code of that extension and it seems as if it has its own metamodel. But it uses the WID-Files to load just some attributes. I am a bit confused if the new custom tasks (email, twitter etc.) are new classes in their own metamodel or if these are just bpmn-conform tasks with additional attributes.
The next thing I would like to know is how the attributes of these custom tasks are set in the BPMN Modeler. In the graphical user interface there is a small button "Configure Work Item" with which you can modify the Attributes. Could someone tell me how this works, if I need to write a Graphiti-Feature for it or if it comes with the modeler and I just have to activate it.
If thats possible I would like to extend BPMN Tasks just with additional Attributes, so that everything is still BPMN conform. Later on I have to write a program, that loads a BPMN diagram and does some checks. Here I need to know if the Task is a specific "Custom Task", so there should be some kind of identification I can use. I hope someone can give me some tips and if the jbpmn extension is maybe exactly what I want (besides the WID-files, I dont need to customize the attributes of the new tasks, I know them already and dont need more in the future).
Thanks in advance,
