[rules-users] Problems saving BPMN2 diagrams in Guvnor

[Cristiano Gavião]

Hi,

I'm playing with Guvnor from jbpm-5.2.0.Final-installer-full using Jboss 
AS7.  I'm using  the Chrome browser

I could create a bpmn2 diagram and play with it. After save it, 
sometimes I get a blank canvas and sometimes it is not saving the changes.

I can open the file and see all my saving messages on the Version 
History folder, but when I try to open it..., it is blank...

Normally I couldn't see any error message at the console when it just 
don't save the last change. but right now, that I lost all elements of 
my diagram (I mean, there is a blank canvas) I got this:
