[rules-users] BPMN editor not working

I'm trying to move from Drools 5.1.1 to 5.2 and I'm reworking my .rf files into .bpmn files, but I've run into an issue - I use the wizard to create a new file like MainFlow.bpmn. After I create it, I open it using the BPMN2 process editor and all is well. However, if I add anything to the diagram and close it, I get an error when I try to reopen it. "An exception occurred while reading in the RuleFlow XML:null See the error log for more details". Any ideas what might be wrong? Where would I find the error log? -- View this message in context: http://drools.46999.n3.nabble.com/BPMN-editor-not-working-tp3182776p31827...
