Well, I extended the search loop to look like this:
def _getParent(self):
curr=self
while hasattr(curr, 'context') and \
(IField.providedBy(curr) or \
IInputWidget.providedBy(curr)):
curr=curr.context
return curr
Which means that it returnes the first non field non widget
it finds. It kind of does the trick.
One would have though I could just use:
def _getParent(self):
field=self.context
content=field.context
return content
But there is situations where a widget has a widget as it's context.
For instance the default ObjectWidget uses an ObjectWidgetView
as it's view class and when ObjectWidget sets it up it supplies
context=self (e.g. a widget as context).
I don't know why it's designed this way, in my ImageWidget, which
is based on ObjectWidget, I've cut out the ObjectWidgetView and
does every thing in the first view class. I did need to change
the page template to use view instead of context but othervice
it works ok (so far).
If anyones interested I can make the ImageField code available.

Johan
