[Grok-dev] ViewletManager in grok.AddForm

[Christian Klinger]

Hi,

i try to work with pure Z3 viewlets in my grok Application.

I have configured my viewletmanager and my viewlets with
this piece of zcml:

         <browser:viewletManager
                 name="demo1vmprovider"
                 permission="zope.Public"
                 provides=".viewletmanager.INaviManager"
                 class=".viewletmanager.NaviManager"
                 template="viewletmanager.pt"
                 />

         <browser:viewlet
                 name="demo1viewlet"
                 for="*"
                 manager=".viewletmanager.INaviManager"
                 class=".viewletmanager.Viewlet"
                 permission="zope.Public"
                 />

I have included the viewletManager in my master.pt with this statement:

    <p tal:content="structure provider:demo1vmprovider" />

This works just fine.

But i get problems if i try to access an grok.AddForm or an 
grok.EditForm. If i try to access one of these i got this error:

Maybe someone as an idea what to do...

Thanks in advance
