silverlight - Exceptions thrown from the binding type converter -


assume doing validation on text box bound property. on setter property might decorate property following

[regular3xpression("^[0-9]$", errormessage = "must integer.")]

however, if user types in letter in textbox, validation never happen because exception type converter. in other words, if had validation summary connected; display error "input string not in correct format." not desired "must integer".

am missing something? seems broken, there way work around this?
