[Zope-dev] plone.z3cform: ExtensibleForm should not change groups class attribute

[Gerhard Weis]

Hi,

Sorry if this is the wrong list, but as plone.z3cform is in the 
zope-svn. I thought it may be Ok.

There is a small problem in plone.z3cform. The class 
plone.z3cform.fieldsets.extensible.ExtensibleForm has a class attribute 
groups, which is changed by the provided API methods. I don't think this 
is intentional, becuase it makes it hard to recreate additional 
instances of ExtensibleForm. The current behaviour works for forms which 
use already groups, but for forms, where the EtensibleForm creates new 
groups on the fly, it does not work. The attached patch fixes this. It 
also includes a small addition to the Readme, which failes without the 
patch applied, and runes clean with the patch applied.

cheers,

Gerhard
