I would try the following, add to two WAExceptionFilters
- the first handles all errors and has an HTML error handler
- the second handles your specific exception type and has an error
handler that does your thing

If you look at the source of WAExceptionFiler >> #handleFiltered: and
WAExceptionHandler >> #handleExceptionsDuring: you'll end up two two
nested #on:do: blocks which is probably what you want.
