[jifty-devel] passing in args to page regions which include forms

[Andrew Sterling Hanenkamp]

Believe it. Every action parameter to an action is encoded like this:

J:A:F-parent-auto-85bdf599148e8e96c00c26dfc4cb6724-1-S572764

This way action parameters can be processed automatically, linked with
the submitted action or ignored for a non-submitted action, etc. Your
templates want a parameter named:

parent

So you need to set that somehow. The usual way is to load whatever you
need (possibly using the result of the action) and add:

set parent => $parent;

in your dispatcher.
