I've run into a situation where I have multiple levels of validation
going on during a form submit;
1) Form level validation (collected in an IValidationDelegate).
2) Metadata level validation (Collected in my own ErrorAggregator).
3) Database level validation (Collected in my own ErrorAggregator).
I'd like to build one global "MessageBox" component that I can put on every
form to display all three classes of error message together since the user
neither knows, nor cares, which level of the application complained that
"login cannot be blank".
Right now, I've got the MessageBox component up and running happily over my
ErrorAggregator, and at the step where I want to push the errors from the
Tapestry Validation Delegate into my ErrorAggregator (translating as
necessary). I'm sort of stumped though.
So far I've gotten:
IValidationDelegate delegate = (IValidationDelegate) getBeans()
.getBean("delegate");
if (delegate.getHasErrors()) {
// what goes here?
}
I can get the delegate (no problem), but I can't seem to crack the nut to
get at the error objects contained therein. Can anyone help me out here? All
I really want are the error strings; my error rendering will take care of
formatting and rendering them, but I need to know the text to render.
Suggestions?
