Description

Note: A patch is attached for this issue.

There is currently a common case in the Eclipse BPEL editor which inserts an empty "query" element in the to-spec of an "Assign" activity. Ode throws an IllegalStateException stating "XPath string and xpath node are both null". It is arguable whether this is a Eclipse BPEL issue or Ode issue. I feel this is an issue on the editor side, not Ode, however we needed to work around it until the Eclipse BPEL project stops producing empty Query elements.

Fixing this removes one more hurdle for someone trying to use the Eclipse BPEL editor with Ode.

To reproduce this, using the latest Eclipse BPEL editor, simply create a process and create an Assign activity in which a value is assigned to a variable or a message part, but no deeper, i.e. don't specify a query.

Again, this is not a critical fix for Ode, it's something we needed in order to work with the Eclipse BPEL editor and Ode. If the Eclipse editor fixes this on their side, this issue will go away.
