Custom error handler and ajax requests (a4j)

Hi,
I made my own error handler (works like the one described here: 
http://wiki.apache.org/myfaces/Handling_Server_Errors) . 
In the backing bean I use following lines to fetch the exception 
details....

        FacesContext context = FacesContext.getCurrentInstance();
        Map requestMap = context.getExternalContext().getRequestMap();
        Throwable ex = (Throwable) 
requestMap.get("javax.servlet.error.exception");

And everything works fine when an error occurs during standard request 
(eg. when h:commandButton calls a method that throws exception).
But when I switch to ajax4jsf and use a4j:commandButton, requestMap 
contains no information about exceptions...
Does anybody know, how to dig to this exception when using ajax4jsf 
components?
