Subject RE: how to avoid 'generator already set' error in flowscript loop ? RE POST
Date Mon, 26 Jul 2004 09:28:57 GMT
Guys, 

thanks for thinking along, but what I'd really like to do is:

myFunction() {
	success = false;
	errmsg = "";
	while (!success) {
		try {
			[something that also displays errmsg]
			[check and throw error if necessary]
			success = true;
		}
		catch (error) {
			errmsg = "some error message"
			success = false;
		}
	}
	cocoon.sendPage([result]);
}

rather than:

> > myFunction(){
> >     try{
> >         [something]
> >     }
> >     catch(error){
> >         cocoon.sendPage([error message]);
> >         return;
> >     }
> >     cocoon.sendPage([result]);
> > }

so basically I want to redisplay the page with an error message on it until
the user has done everything right.

Bye and thanks, Helma
