In the Jboss Seam application, how can I make sure that every exception results in a custom error page?

Question

I already have the following declared in my pages.xml:

<exception> 
    <http-error error-code="500" />
</exception>

and this is in my web.xml:

<error-page>
    <error-code>500</error-code>
    <location>/error500.html</location>
</error-page>

However, sometimes when an exception is thrown, I get a debug page even when it is in production. I read here that if an exception occurs during the RENDER_RESPONSE phase, redirection cannot occur because the response has already been sent. I have two questions:

• How to determine if an exception was excluded at this stage?
• Is it possible to display a custom error page regardless of where the exception is thrown? If so, how can I do this?
