Hi...

I've been struggeling with f:queue trying to make the "onerror" event works.

I've a filter...

try {
     filterChain.doFilter(request, response);
 } catch (ServletException se) {
     httpServletResponse.sendRedirect(null);
}

And I want that the f:queue to alert "error" without the redirection to the error page.

<a4j:form>








<a4j:queue onerror="alert('Error!');" />








<a4j:commandButton action="#{backingBean.go}" value="Go!" />








</a4j:form>

This works on every browser except Opera. Opera will call the "onerror" event if hay throw the exception instead of send a null redirect.

Is there a flag or a status I should set on the response to make this works?
