Hi!

I have one problem in designer.

I create a new simple process, with an start and end node, in the designer inside guvnor 5.4. I save it.

Then, I update the process using Guvnor Rest API. I make a PUT to   http://localhost:8080/drools-guvnor/rest/packages/TestNewPathways/assets/myprocess/test http://localhost:8080/drools-guvnor/rest/packages/TestNewPathways/assets/myprocess/test/binary, with content type application-octet stream, passing the string.getBytes of the modified bpmn. 

Then, I go to the designer, and I can see the changes into the process. But then, I try just to save the process there and I get an error into the screen, and an exception in logs that I will paste below. Any ideas of what could it cause it?

Thanks!

Demian
