component event exception, handling in page with onException method

[Chris Mylonas]

hi users,

i'm having trouble catching a component event exception.  it's on a zone
update.

at this stage in development, i want to catch it and just reload the page

    Object onException(Throwable cause) {
        String message = cause.getMessage();
        logger.info("BASTARD");
        return this;
    }

I'm not seeing my "BASTARD" message in the server log, and i'm not getting
the page reload.

I am just seeing the javscript pop up exception (for the zone update)

This is with tapestry 5.3.7

Any pointers appreciated.

The exception is coming from an EJB.  Something doesn't exist in this zone
update preview mode e.g. the user wants a sneaky look behind door number 3,
when door number 3 doesn't exit."

Cheers
Chris
