Accessing form fields in a reactor

Hello All,

I recently had a request where users would like to be able to create a 
new message for an issue and also have it generate and send an email 
containing the message text - but only for some new messages.

The idea would be that a user ticks a checkbox before clicking on the 
submit button to indicate that they want the email to be sent.

 From what I can tell there doesn't seem to be a way of checking if the 
checkbox has been ticked from inside a reactor - without adding a new db 
class field to the issue/message... which doesn't really make sense in 
this case.

Does anyone have any suggestions on how to approach what I am trying to 
achieve?

At the moment I think I might be stuck with having to create a new Action.

SeeYa,
John.
