Error setting Business Object property

Q&A
1

Hello All,

We have a business object loaded into a business variable from the database at the start of the process.

At some point, we have a simple service task that has a single operation which sets an object property to the Integer 1:

newIssue - setStatus - Constant java.lang.Integer:1

However, this task fails with the following stack trace:

The server complaints about a NullPointer Exception, however the business variables is set (it’s been used in previous tasks with no problem) and the value set is a constant.

Thank you.

Ok. The problem was we were adding a test record directly into the database and we left the PERSISTENCEVERSION in null.

After trying with a new record with that field in 0, it worked with no issues.

I hope this is useful for anyone with a similar problem.

To add more information: I created a new BDM object and I assigned values to a new instance using the “instantiated with” operation and it works perfectly. It’s only this simple lonely assignation that is not working.

Also, we’ve verified the instance we are trying to update is valid by logging it’s properties and indeed it is.

As you can see in the stack trace above, the problem has nothing to see with the model itself, but it seems like a platform bug or I’m missing something too obvious.

Any hint very welcomed.
