What is the recommended way to handle a Cancel button on a form? The
expected behaviour would be to clear the internal state, bypass
validation and move to a different page. I tried:
@OnEvent(component="Cancel")
String onCancel()
{
surveySession.setSurvey(null);
return "Start";
}
where "Cancel" is the id of the submit component but Tapestry
complains that this method cannot return a String:
Event 'selected' from org.byteberry.survey.pages.SurveyDetail:cancel
received an event handler method return value of Start from
org.byteberry.survey.pages.SurveyDetail.onCancel() (at
SurveyDetail.java:46). This type of event does not support return
values from event handler methods.
On the other hand, if I try do do it on the form events I don't know
which button was pressed and I cannot bypass validation.
Is there a straightforward way to do it?
Thanks,
Bogdan Calmac.
