String persistence db4o

Hi,
Is it possible to persist string values using db4o?
I was under the impression that it was possible, however all the string values I try to persist using db4o end up op having a value of 0, so Iā€™m a bit confused.
Anybody?

Thanx,

Jesse

Yeah, I got confused, db4o persistence works fine, habmin shows me 0 instead of the string value.
Case closed I guess.
