Issue

• We use the WYSIWYG editor that we installed from : https://access.redhat.com/jbossnetwork/restricted/softwareDownload.html?softwareId=41481.
  If I move/drag a node in the existing diagram to make space to add other nodes, I start getting errors when I am using the diagram in my test cases. Please note there has not been any modification done to any id, connection or properties. It’s a simple drag and move.
