Re: RequestCycle with multiple handlers

[Nick Pratt <nb...@gmail.com>]

I figured this out - the handler was being invoked by the JS component in
two different places - one using Wicket.Ajax.get() and the other by direct
jquery Ajax invocation (same callback URL).   I swapped out the plain
jQuery invocation for a Wicket.ajax call and everything works as expected.
