Hello,
Our system is based on Windchill 8.0.
We have a problem with workflows.
After having upgraded a process by import et have modified a few tables , we have the following error (Sorry, it's in French):
wt.pom.DatastoreException: Erreur de persistance. Message d'erreur système :
Exception imbriquée : java.lang.NullPointerException
... and that's it !
The system does not create more instances of the modified process, and expecting the same error for other "not change" process.
Some of the other instances of the process are not viewable.
The error is not very verbose , and I did not know which track search.
For information, the process was checked out. We've deleted the last iteration process, but we always have the problem.
Can anybody help us?
Thanks.
