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/...
http://localhost:8080/drools-guvnor/rest/packages/TestNewPathways/assets/...,
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
