Hi,

I'm using ZODB in a desktop app (i.e. not using zope).

I have class A which contains a list of instances for class B.

I can persist class A when the list of class B is empty. When i add an instance of class B to the list (and set _p_changed = 1) i get the error:
"TypeError: can't pickle PySwigObject objects"

Can someone please give me a link of some advice in how i go about persisting lists of class instances?

Thanks,

Jamie
