I have a question regarding the workflow container element Predecessor Workitem.
I want to use it in the following scenario. I have a user decision and in one branch from that decision a sub workflow is called.
In the sub workflow i need to get the work-item ID from the User decision step.
I tried to do binding from UD task container to WF container and from WF container to SubWF container but it comes up empty. This, i read, is because these are elements from the container that are done by the system.
I've also read quite some notes on the subject. But none are very clear on how it should work.
So my question is: how should i then get a value in the _Predecessor_WI field in the Workflow container?
