-------------------------------------------

Thanks Peter. Just fixed this  by replacing isUndefined with it's meaning. Can 
you try again with SVN head or the nightly version of today?`

regards,

Martin

> Hello,
> We're using MyFaces-1.1.1RC3. 
> The HTML link's "onclick" rendered by 
> org.apache.myfaces.renderkit.html.HtmlLinkRendererBase#renderJavaScriptAnchorStart
>  goes as following:
> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
> if ( document.forms['id'].onsubmit )
> { 
>       if( document.forms['id'].onsubmit()) document.forms['id'].submit();
> }
> else
> {
>       document.forms['id'].submit();
> }
> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
> Which means "If form has 'onsubmit' handler and it's return value is 'true' - 
> submit the form". But it should be the other way around - "If form has 
> 'onsubmit' handler and it's return value is 'false' -don't submit the form". 
> The difference shows up if "onsubmit" handler returns nothing and return 
> value of calling"onsubmit() is "undefined" - in this case "if ( 
> form.onsubmit())" doesn't hold true and "form.submit()" isn't called. The 
> result - you have a form with "onsubmit" handler returning no value (it's 
> perfectly Ok) with non-working links, i.e clicking them causes no effect.
> I believe the JavaScript code should be written in the following way:
> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
> if ( document.forms['id'].onsubmit )
> { 
>         var result = document.forms['id'].onsubmit();
>       if( isUndefined( result ) || result ) document.forms['id'].submit();
> }
> else
> {
>       document.forms['id'].submit();
> }
> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
> So far - we've just made our "onsubmit" handler to return "true" explicitly.
> Thank you !
