OK, here's what I can surmise thus far: - Only 'wicket:interface' JS requests - from 'onchange' Ajax validator or from a SubmitLink-initiated form submission trigger the exception - the form being submitted or validated is in a couple of pages but *never *in *StateProgramDetailsPage* - the exceptions thrown only cites *StateProgramDetailsPage* - pages are mounted using HybridURLCodingStrategy and have a common (concrete) super class - in all wicket:interface requests resulting in the exception: pageId = 0; 'version' is always empty (thus wicket defaults to 0)
So, in summary, *sometimes* form component Ajax validation or non-Ajax form submission wicket:interface POST requests results in retrieval of the incorrect page - StateProgramDetailsPage - from PageMap. Consequently, the exceptions are thrown. I would appreciate any general thoughts, but also answers to these questions (to help us understand what goes on under the hood): - What logs should we enable to see why an ajax wicket:interface from one page resolves to another page? - Does Wicket Ever manually write out JSESSIONID? In 'wicket:interface' requests specifically? or is that left up to the servlet container? - What is PageMap's scope - one per HttpSession? - What's 'urlDepth'? - What's the lifecycle of a IRequestCycleProcessor and IRequestCodingStrategy? Is newXXX called only once per app? - If we wanted to rule out DiskPageStore by installing an in-memory page store instead how can we do so?
