Workflows developed with Designer extension show blank without extension
We have developed an Actviti Designer extension that holds some custom tasks for our application. If I develop a workflow containing the custom tasks from the extension, and then load the workflow in a vanilla version of Designer, i.e. without our extension installed, I get a totally blank workflow.
If I re-create the same workflow without using our custom extension and compare, the "activiti:extensionID" attribute on the "<serviceTask>" tag is the only difference. For example:
Is there an easy way to make the workflow be editable without my custom extension? It is very confusing to our users. We could strip the "activiti:extensionID" attributes, and I think that would make it work... but I'd rather not do that.
Edit: If I remove the "extensionID" attributes, the workflow shows up just fine without our Designer extension being installed.
