WICKET-606 - Stateless forms with QueryStringUrlCodingStrategy

[Al Maw <wi...@almaw.com>]

At the moment, stateless forms are broken if you use the 
QueryStringUrlCodingStrategy.

http://issues.apache.org/jira/browse/WICKET-607

As the comment says, the issue here is that WebRequestCycleProcessor is 
looking for a component path before it looks for mounts. And once it has 
found a component path, it's trying to resolve a rendered page for it. 
With stateless stuff, there is no rendered page available in the 
PageMap, so you get a PageExpiredException.

Even if we fix this (put in an ugly catch block, for example), things 
still didn't work, due to QueryStringUrlCodingStrategy not knowing about 
BookmarkableListenerRequestTargets (see the special-case code in 
BookmarkablePageRequestTargetUrlCodingStrategy.decode() for example).

I fixed that in trunk in r544204, only I'm now not sure I've done the 
right thing - I think maybe we should be calling 
AbstractRequestCycleProcessor.resolveBookmarkablePage() instead, as that 
does much the same thing.

I'm not sure what's best to do here, and would appreciate some help from 
someone more familiar with the code.

Regards,

Al
