enStateFrom
CATollState constant specifying the previous state of the toll.
Error Codes
If the method fails, an error is raised and Err.Number is set to a value other than zero.
Return Values

This helper method signals a StateChanged event. If the state switches from unselected to selected, this method also unselects the toll that was previously selected.
