[Zope3-Users] Widget Error on direct __call__ with pt

[Dennis Schulz]

The error occurs when try to get the widget structure of the 
objectwidget in my page tamplate:

   
tal:content="structure widget">

   
In the earlier version (with the html dirctly in the call method) this 
was necessary.

Is there a problem with ZopeTwoPageTemplateFile?

[Zope3-Users] Widget Error on direct __call__ with pt

[Dennis Schulz]

Hello,


I am using the following code for a sequence widget.


class TableRecordSequenceWidget(ListSequenceWidget):
   def __init__(self, context, field, request, template_='', 
subwidget=None):

   super(TableRecordSequenceWidget, self).__init__(
   context, field, request, subwidget)
   def __call__(self):
   render sth


It works good as long as I write the rendered html directly in the 
__call__ method.
But after a while it gets dirty, I would like to have it in a page 
template..


However when I try to change it to return a page template in the call 
method,


(like I found it in many examples)

   def __call__(self):
   class TemplateObjectWidgetView(ObjectWidgetView):
   template = ZopeTwoPageTemplateFile("itemwidget.pt")
   template = TemplateObjectWidgetView(self, self.request)
   return template()

I have the following error:

Any help? Again, the version without the page template works perfectly

   
tal:content="structure widget">
