Mauricio, thanks for your reply. That clarifies one thing (although I thought I saw something related to "wait for completion" functionality in the Eclipse modeler plugin).
So, inside the work item handler, this method is implemented:
executeWorkItem(WorkItem workItem, WorkItemManager manager)
So, how do I start from a WorkItem object and set the wait for complete flag. Can you please show a simple example. I only seem to find examples of how to do it when constructing the model programatically node by node.
Thanks
