Hi Maciej,
Thanks for your help,
I tried to debug to understand where does it come form, when skipping this task the status was "Completed" so there was no match with the list of command 'Created', 'Ready', 'InProgress' ...
But this does not explain why the task is being skipped in the first place (maybe a cache issue).
I'm trying to move jbpm on mysql db (my application will remain on a postgres db), to check if this have any relation.
I will work on the junit test once I finish setting the mysql db (heopfuly by the and of the day),
here the process definition file.
