local data storage in forms?

A common case, I suppose: you have a transient field in a form that is only used to support a decision or to be copied into a real field. Example: a drop down box with the widgets (in a multi-widget form) near a button "Duplicate Widget". The action behind the button would duplicate the model part of the indicated widget so it will have to reference the currently-selected item in the dropdown box.

The orthodox MVC approach would be to store that entry in the model (perhaps a difference instance named 'local-data').

Is there a simpler way, though, for non-submitted data? In this case, I simply want to reference the value chosen in that dropdown box so I can use it in the "origin" attribute of an insert action.

Thanks,

Like you said, using a separate instance for this is the way to go. I
often have an instance called "ui" that stores this type of state
which is very much tied to the way the UI is done, and which is never
sent to services. Plus"ui" has the the additional benefit of being a
short name :).
