Sorry I have just find what I wanted:
Let's say I have:
``
name: load_action
action: saisie
controller: default
ajax: True
``:widget
where :
def saisie():
....
return dict(stuff=stuff)
saisie.html is :
{{extend 'layout.html'}}
<h2>{{=Selection}}</h2>
<h1>{{=CArt}}{{=ArtOF}}</h1>.....
I just needed to do this in saisie.html :
<h2>{{=Selection}}</h2>
<h1>{{=CArt}}{{=ArtOF}}</h1>...
and every thing is all right my view is embed without beeing twice
rendered
by the way in saisie.html, this
<!--
{{extend 'layout.html'}}
-->
<h2>{{=Selection}}</h2>
<h1>{{=CArt}}{{=ArtOF}}</h1>...
does not produce the same result (jquery stuff appears)
