[Zope3-checkins] CVS: Zope3/src/zope/app/interfaces - form.py:1.5

[Stuart Bishop]

Update of /cvs-repository/Zope3/src/zope/app/interfaces
In directory cvs.zope.org:/tmp/cvs-serv24906/src/zope/app/interfaces

Modified Files:
	form.py 
Log Message:
- Make Widget validation errors humanly readable, it a half-arsed sort of way.
  Widgets have spawned an 'error' attribute, set by getData.
- Display validation errors next to the dud input in Widget.row()
- Make description a tooltip of a Widget's label. This is currently done
  by abusing the <acronym> tag.
- addwizard and editwizard work again with the recent editview changes
