[Grok-dev] How to create Cancel that doesn't validate form in grok.EditForm

[Sebastian Ware]

Thanks both! This worked like a charm. I added:

   NoValidation = lambda *args, **kwargs: {}

and then imported it, allowing:

   @grok.action('Cancel', validator=NoValidation)

I agree that it would be great to have something like "NoValidation"  
available out of the box, I hope it makes it into the 1.0 so it is  
included in sample code and tutorials.
