Property UpdateSourceExceptionFilter
UpdateSourceExceptionFilter
called whenever any exception is encountered when trying to update the value to the source. The application author can provide its own handler for handling exceptions here. If the delegate returns null - don't throw an error or provide a ValidationError. Exception - returns the exception itself, we will fire the exception using Async exception model. ValidationError - it will set itself as the BindingInError and add it to the element's Validation errors.
