You can implement the xValidationErrorHandler interface to handle the x-validation errors.
public interface xValidationErrorHandler { public void handleError {Exception e, ChannelContext channelCtx, PresentationHandler prsentHandler) ;} }
You can define xValidationErrorHandler in btt.xml > ChannelHandler > HTML.
If xValidationErrorHandler is not defined in btt.xml > ChannelHandler > HTML, the default handler will be used for server side x-Validation error. The default behavior is to render UDTT error page and print error in browser and in log file.
