RE: how to avoid 'generator already set' error in flowscript loop ? RE POST

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
