process graph and removing process definitions

[tom.baeyens]

on behalf of Marcin:

I have another question concerning process graph image - the one displayed while inspecting process instance. I tried to plug it into process definitions managemenet but I found out, that it requires two files:
processimage.jpg and gpd.xml. Tag that renders the graph works only with process definition with these two files. That is why I will not be able to use it to show process definition unless there is a plan to generate it dynamically according to process definition...

I switched to removing process definitions and came across such an exception from hibernate. I think it has something to do with synchronization of hibernate objects in the session. I saw one test that delets process definition, I will look into into and find out why this exceptions occurs now.

[tom.baeyens]

does your code break anything else in the webapplication ?

if not, you can check in your code so that i can have a look...

regards, tom.

[mmieszek]

This code is seperated from the rest of application. I'll check it in once I have access to the cvs repository.. I am waiting for reply from forge admin.

Kind regards,

Marcin
