Vedr.: Re: NullPointerException?

[dt...@sparnord.dk]

Hi,

Sorry, I should have mentioned, that yes the two classes are annotated as 
entities.

It seems the problem may have been related to me forgetting to på an 
@PersistenceUnit annotation on the class.

However, I have tried adressing the problem in the meantime by changing 
the relationship to be many-to-many. But for some reason this just leaves 
the collection as "null" in all circumstances, even though lazy fetching 
is used (by default).

Hmm - help appreciated :)
