[Zope] OOBTree's and persistence problems

[Christian Theune]

Hi,

I have some problems with OOBTrees and the persistence machinery - I think.

My situation is following:

a class has an attribute 'pkgDB', which is an OOBTree.

When I assign a value to a key ( e.g. pkgDB['key'] = 'value' ) in a function call,
then the value is set. When I know restart Zope, the value is still there - as I expected
it to be.

Now, when I assign another OOBTree as a value to the first tree ( pkgDB['key'] = OOBTree() )
I can also assign values to the tree and see the values in later transactions, so it gets committed
correctly.

But when I know restart zope, the changes made to the OOBTree seem to be lost. So I think the ZODB
doesn't recognize the change to the embedded OOBTree. The same is also with PersistentMapping.

Regards

Christian
