Creating a process flow - Unable to parse xml, Null Pointer Exception

rsunkara48 Jun 28, 2016 10:43 AM

I am using BPM Suite 6.3 and EAP 6.4.6 (Installed EAP 6.4 and applied patch on top of it)

Its successfully installed and I could create a process flow. I have created only a start element, a manual task (added description and assigned it type of manual) and the end element. The moment I add any task, I see unable to parse xml in the bottom messages window and If I save it and reopen it, it never opens in the graphical editor, I see a pop up message - Unable to process, opening in xml editor. Below is my xml. I have seen others facing this issue in april 2016 and the resolution as below. If this really solves the issue where exactly should this be placed?

o import a process back it is necessary to manually add the process variable into the underlying XML definition.
- Add ItemDefinition <bpmn2:itemDefinition id="_sampleProcessVar" structureRef="Boolean"/>
- Add the actual variable (property) <bpmn2:property id="sampleProcessVar" itemSubjectRef="_sampleProcessVar"/>

Once the process is imported, it is possible to delete the process variable again and also the task input/output assignments where it is used.

1. Re: Creating a process flow - Unable to parse xml, Null Pointer Exception

I cant believe simple solution is pointing to Java 1.7 and my system was pointing to 1.6
