I'm tracking down a bug where a stateless form submission isn't working if I
reboot my tomcat server. The issue is that Wicket doesn't recognize the
wicket:interface parameter that is passed down.
I believe I've tracked down the problem to this code in
BookmarkablePageRequestTargetUrlCodingStrategy:
// do some extra work for checking whether this is a normal
request to a
// bookmarkable page, or a request to a stateless page (in
which case a
// wicket:interface parameter should be available
final String interfaceParameter = (String)parameters
.remove(WebRequestCodingStrategy.INTERFACE_PARAMETER_NAME);
if (interfaceParameter != null)
{
WebRequestCodingStrategy.addInterfaceParameters(interfaceParameter,
requestParameters);
return new
BookmarkableListenerInterfaceRequestTarget(pageMapName,
(Class)bookmarkablePageClassRef.get(),
parameters, requestParameters
.getComponentPath(),
requestParameters.getInterfaceName(),
requestParameters.getVersionNumber());
}
The issue is that the 'parameters' will never contain the
INTERFACE_PARAMETER_NAME because it would have been removed in
WebRequestCodingStrategy:decode:215 which as far as I can tell is always
called first (from RequestCycle.step.RESOLVE_TARGET:1233).
The 'requestParameters' should already have the interface parameters, so it
isn't clear why the addInterfaceParameters() logic is being called again (it
is already called in WebRequestCodingStrategy:decode:200).
In what case was this logic necessary? Being new to the code base, I don't
know every possible code path, so perhaps there is a different way of
getting to this point that I'm not seeing.
