Hi Ronald,
I just found some time to try it out.

It returns true. Just adding them doesn't persist them, so this has to work.

That causes a ClassCastExcpetion:

Very strange. What is happening here? I have a workaround (maps) for my proto
and am thinking about Seam and other solutions, so this is not to urgent for
me.
But persistence layer being broken will probably cause bad problems along the
way?
