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

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
