Hi all,
Yesterday I installed the BPMN plugin and made a BPMN diagram on which I
worked all day without any problem.
However, when I tried to open it today I got this message:
-----------------------------------------
Error opening the editor.

I have deleted the whole eclipse directory and installed the plugins on an
eclipse fresh install: same problem.

Any idea?

Thanks.

Hi David,

which version of BPMN are you using ? it sounds like the latest version
avoids the exception. The bad news is that the diagram is most probably
corrupted, and the association edit part resolves the diagram as its
semantic element.

Please try to grab the 0.8 version of the BPMN modeler on the update
site, open the diagram and delete the faulty association if you see it.

Thanks.

Antoine

Hi Antoine,

I was using the 0.7.0.200710161054 version, so I followed your advice and
installed the 0.8 version. The diagram was opened without any issues.
However, as you guessed, some diagram elements exhibited some bad
behaviour (inability to change some properties or to delete them).
Luckily, I managed to delete them by manually editing the xml code, and
then I recreated them in the graphical editor.

Thanks for your help.
