Called when a transaction created by the core design surface throws an exception. If this method returns true the exception is swallowed. Otherwise it ripples up to the default .Net Framework exception handling code. Derived classes can override this method to customise exception handling and error messages. The base class returns false, meaning that all exceptions will be thrown up.
