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

Afair expected behavior, script errors on the JSF side are only exposed in dev 
mode or if an error listener is explicitely set.

I think it was part of the spec... but I really have to look this up.

 So if you apply an error listener you can do whatever you want with the error 
info.

> I was looking for a bug in our scripts happening on submit of the form. 
> Unfortunately the JSF-Javascript submitting the form 
> (myfaces.oam.submitForm()) is swallowing exceptions that occur while 
> submitting.
> try {
>     form.submit();
> }
> catch(e) {
> }
> Maybe one could do some kind of logging there to help debugging.
> try {
>     form.submit();
> }
> catch(e) {
>     console.error(e); //?
> }
