How did you load an Object from the database? You are running WAS6, is that WAS61 with the FP? A code snippet may help.
If you use OpenJPA APIs to load data from your database, you shouldn't need to call merge on that object. Is it possible that your transaction isn't being committed and that is why your changes aren't being persisted? -Rick Gerlex wrote: > > Hello together, > > I have one big problem!!! > > I want to update an Persistent-Entity with the merge-method and it doesn't > update the attributes, > which I have set to null. > > For example: > > 1.
