[Zope3-dev] Possible bug in editform

[Garrett Smith]

I think this is bug, but wanted to get feedback from the list.

When you update an object and the form has widget errors, any values 
that were successfully updated by widgets (i.e. no errors) are committed 
to the database.

I suppose this could be viewed as a feature -- the form applied whatever 
changes it could. But this behavior surprised me -- I would expect that 
either all modified values are updated, or none are.

As to the solution, I have a get_transaction().abort() in the edit form, 
where it handles the widgets errors.
