reference input page from inside action?

[Seth Ladd]

Hello,

Is it possible to reference and forward to the input page of an action from
within the action?  It seems as if I have to make an explicit forward
mapping for input for each action.  Sometimes, I need to do extra state
checking inside action, and if that fails, to forward back to input.  The
explicit forward mapping is fine, but it would seem more simple if "input"
was a default mapping.

Any tips or pointers would be much appreciated!

Thanks,
Seth
