Yes, please have a look at the org.eclipse.bpmn2.modeler.examples.dynamic sample project, specifically the SampleCustomTaskFeatureContainer's getAddFeature() method. This describes how to change the shape of a BPMN2 element as well as adding icons and changing the gradient color.

HTH,
Bob

Hi everyone,

I'm changing the color of my elements through AbstractCustomFeature. It's available here [Line 93]

The issue here is that the new color is not have been persisting. When I close the model and open again, the new color was replaced by default color.

I guess the setFillColor method [Line 93] should be added in another place to persist the changes. Which place should be?

Hmm, I wonder if it's possible that the color is not being saved in the bpmn XML, and when the file is reloaded, the editor just applies the default colors?

When you say to reload the file, is it means just refresh the file or something else? I made a screencast, the editor just applies the default color if the file was closed and reopened. Nothing happened when I refresh the file.

To solve the problem I added the setFillColor() at org.eclipse.bpmn2.modeler.ui.features.activity.task.TaskFeatureContainer.getAddFeature(...).new AddTaskFeature() {...}.decorateShape(IAddContext, ContainerShape, Task).

Now, when I close the diagram and open again, I won't lose the previous changes.
