Hello Jonah, Thanks for the reply. On Wed, 2011-06-08 at 09:53 -0700, Jonah Crawford wrote:

Joshua - persistence in zope occurs based on assignment of values. You have to explicitly assign the values your form collects to the object you're persisting. That object then gets pickled to the ZODB as long as there's an assignment to an object in the ZODB. Events have nothing to do with it.

Post some code examples if this isn't helpful enough.

I was trying to add a non persistent object to the BTreeContainer. I was of the notion that I don't need to make my object persistent explicitly, as I am adding it to the persistent btree container. The add operation was successful but the modify operation on my object failed to persist. Making my object persistent solved the issue. -- Joshua Immanuel HiPro IT Solutions Private Limited http://hipro.co.in
