Change in Description Rule invalidates Journal Entry Rule Set

Summary:

Have an issue also with the WIP Variance when setting up Journal Entry Rule Set. It was the only JERS that would not allow Subinventory at the line level. And seems it is the only transaction that is not having Subinventory as a source (for the JERS we are hitting).

Once I linked a Description Rule that worked, all is fine. Then I added a 2nd prio to the Description Rule. Project related or not and show project. Again it worked for all my JERS but again, WIP Variance JERS went into error.

So created a new Description Rule for WIP Variance that had old rule without the project field. When going into the JERS, the UI giver errors on null values and not showing the line rules linked anymore. I can select the new rule, but saving fails with same null pointer error.
