Created attachment 800007 [details] stack-trace.txt Description of problem: If I try to save the attached process (process-image.png) then editor says save OK but changes where in fact not saved. The attached error (stack-trace.txt) will be present in the log. Based on the error-message - if the editor does not know how to handle the definition then it should properly inform the user. The 'view process sources' feature does not share this shortcomming. It informs the user that the conversion failed.

We currently do not support nested swimlanes. Only lanes nested inside pools would make sense, so we will add a new BZ to allow multiple pools to be used in Designer. Current fix for this includes not allowing in the UI for users to nest swimlanes, and to handle errors like in the view source option.
