Re: Exception redirecting to source page
Thanks for the reply.
I think I will not use onRuntimeException to control my 'business
exceptions' even if it works now. If Wicket doesn't count on such thing, I
have no guarantee that it won't break in the future.
I'm not sure it will not break in the future.
What I'm afraid
of changes in the Wicket code in future versions that could break my

problem as most wicket processing has already happened.

I did something I think it dangerous. Something like:
public Page onRuntimeException(Page page, RuntimeException e) {
