Problem with Eclipse Plugin Camunda Modeller

[d200...@yahoo.com]

Hi,

i'm using Eclipse Plugin Camunda Modeller to model BPMN 2.0 and it has worked properly sofar. When i tried to model CallActivity and saved it, it failed. So i couldn't edit the BPMN file and save it properly in Eclipse. The reason were some kind of StackOverflowError:

The following resources could not be saved:
URI: platform:/resource/anzeigengenerierung-workflow/src/main/resources/workflow_abo_excel.bpmn, cause:
java.lang.StackOverflowError

Do you guys have any idea how to fix this kind of problem. Is it a bug with Eclipse Plugin Camunda Modeller. By the way i'm using Eclipse Luna. Thanks you in advance.

Hi Nam,

These kind of issues are typically hard to reproduce. Does this problem repeatably occur when you perform a certain action like adding a call activity in a specific process or is it rather random?

Cheers,

Hi Thorben,

it only occurs when i try to add a call activity and save the BPMN model. Maybe it is some issues with Eclipse Luna cause it happens only when i use Plugin Camunda Modeller inside Eclipse Luna. With other version like Eclipse Kepler i have no problem at all.

Best Regard

I have the same error (see http://postimg.org/image/3sakxyp8p/
). It occurs within a brand new Eclipse Luna as well as Eclipse Mars. Just install Eclipse Luna/Mars Java EE Edition and add the Camunda Modeler (Latest Kepler Edition).
I think the error is related to https://app.camunda.com/jira/browse/CAM-4228. As the development environment is an essential success factor I hope this bug will be fixed soon :-)

Hi Gunnar and Nam,

as we don't support Eclipse versions later than Kepler [1] currently I would like to recommend to use the Standalone Camunda Modeler. Although the modeler is not integrated in your IDE you can easily run it beside your latest version of the Eclipse IDE.

Cheers

Michael
