[Zope-CMF] validateMetadata

[Antwan Reijnen]

Hi Tres,

your help is very much appreciated, thanks again. 

I wonder however: suppose the metadata is not valid. I first have to store it, and ony AFTER storing takes place, I can test it.

Is there for that situation a way to rollback the editMetadata call? I'm not a undo / rollback-expert :-) so sorry for asking the obvious.

Greetings, Antwan.
