I have created a Configurable Action (where 'configurable' => TRUE) and I would like to provide the ability for the user to use either the nodereference_explorer or node relationships widget.

The nodereference explorer looks like an actual "widget" but I don't find any documentation indicating how to use it.
The node relationships module looks more like it isn't a "widget" (there is no hook_widget_info implementation) but looks more like a form_alter implementation, and the internal implementation requires a "node" object (which of course doesn't exist since there really isn't a "node" in the Action, and even if I wanted to set one in the "context" which one would I set? It really doesn't make sense in this case.)

How would I go about using either of these in the way I have indicated?
If I knew where to begin and had a bit of a "push" I think I could get one of them to work (I'm a programmer with 12+ yrs experience, just not with Drupal :) )

Also, if I have posted this in the wrong place, let me know. I could post these in the "issues queue" of either module, but this seemed more general than specific...still, I realize sometimes that is where posts like this belong.

Thanks in advance.

Andrew.
