[Zope3-Users] formlib.form.Action.render()

[Christian Lueck]

Hi there!

I have a problem with formlib, form.Fields are rendered correctly :) but
I got stuck with Actions
Well, I followed the lines of formlib/form.txt
but adapted the examples for use with ZPT by overridding the template
method:
template = ViewPageTemplateFile('mytemplate.pt')

The widgets are rendered one by one by methods in the viewclass which
return self.widgets['field_x']()

That works fine :-)
But when I try to get the action-objects rendered there is an exception.

class Myform(EditForm):
    <snip>
    def renderActions(self):
        result = []
        for action in self.actions:
            result.append(action.render())
        return '\n'.join(result)

The action.render() call causes a component lookup error:

<snip>
Module formlibexample.browser, line 89, in renderActions
    result.append(action.render())
  Module zope.formlib.namedtemplate, line 61, in __get__
    return component.getAdapter(instance, INamedTemplate, self.__name__)
  Module zope.component, line 141, in getAdapter
    raise ComponentLookupError(object, interface, name)
ComponentLookupError: (<zope.formlib.form.Action object at 0xb01acb6c>,
<InterfaceClass zope.formlib.namedtemplate.INamedTemplate>, 'render')


The page is registered with the <browser.page> directive:

<browser:page
      name="AddOrder.html"
      for=".interfaces.IOrder"
      class=".browser.OrderEditView"
      menu="zmi_views" title="Edit Order"
      permission="zope.ManageContent"
      />

What am I doing wrong?


Kind regards,
