Can't create a new form on a widget

[sharvey]

Making a new form on a widget isn't possible. Well, only half possible.

Making the form show is fine, however, you cannot create a form action on a widget because the controller needs to execute the form action, and that isn't possible if the form action is on the widget class.

Also, there is no easy way to figure out the controller that a widget is related to.

Apparently this has been done, but we need to get some confirmation. Sean, can you track down an example of a form in a widget?

I believe that the idea is that you make a (WidgetName?)_Controller class, and attach the form to that. However, we could probably do with some documentation on the widget development docs.

As it turns out, you can create a form on a widget by making a separate (WidgetClass?)_Controller class and putting your form on there. A more elegant system can come in 2.4.
