Listener question
Hello there! AFAIK (I might be wrong) a form event listener is called twice
after a submit is pressed right? One for rewinding phase, and the other is
the "normal?" phase. Well, I have a form where my method is being called
twice, but both on the rewind phase, I put a simple cycle.isRewinding() if
statement on it and it always pass there.
My problem is that I do some DB checking on this in order to validate some
input fields, I was expecting that by doing:
if(!cycle.isRewinding()){
checkConstraints();
}
Would work, but it's never called, instead the rewind phase happens twice.
I've searched the archives for this (I've seen this before) but could not
find.
Any ideas for this?
Regards
Problem with Form in IE6?
Posted by Siddhartha Argollo <sl...@tre-ba.gov.br>.
Hi there!
Is anyone else having this problem with form submissions in IE6?
When I try to submit a form in IE 6, I keep returning to the home-page
and the listener method is not executing. The same page works fine in
firefox.
To be sure that I wasn’t making mistakes, I copy-and-pasted the example
found at the quick start of the tapestry page.
I’m using tapestry 4.0, but this was happing with the beta versions too.
I really don’t know if this is a bug or just my lacking of experience in
tapestry.
Thanks for any help.

Ron, the output... Here's a snippet:
public IPage onSubmit(IRequestCycle cycle) {
if (getDelegate().getHasErrors())
return null;
if (cycle.isRewinding()) {
System.out.println("rewinding");
} else {
System.out.println("normal");
}
checkPassword();
checkLogin();
getUserService().register(getUser());
return getResultPage();
}
The "rewind" output is shown twice.
Regards

for example: you use the same listener on your submit and on your form...

Hum, but what could be causing the rewind to happens twice?

you are wrong :)
the listener is called only once.
you should use the rewind cycle to validate user input.
the (normal) render cycle should always "work" to the current state of
your page/application -
what should checkConstraints() do ? check if something is wrong? doing
it on rewind is the right time...
Cheers,
Ron
