Hi Ralph,
It worked. So I created a custom task and now I want to play around with the shape of it, but it isn't working. I have attached files, please let me know if there is something wrong with it?

yes this tutorial did not show the perfect way to implement a runtime extension. I learned a lot during writing this tutorial ;-) But we added the results of this work to the Wiki Page of the Eclipse BPMN framework with a lot of additional information: https://wiki.eclipse.org/BPMN2-Modeler/DeveloperTutorials Here you will find the more accurate tutorials which will help you to develop an extension. Also a good starting point is to take a look on the BPMN example plugins here: https://github.com/eclipse/bpmn2-modeler/tree/master/examples/plugins I think this can help you to get started with you own extension.
