2019-04-27 notes

I think what needs to happen is that things need to happen in the following order:

• detect submitted page - $this->GetPageKey_forData();
• detect requested page - $this->DetectPageRequest();
• determine page to show - $this->HandlePageRequest();
  • calculate if requested page should be displayed
• load all form controls needed to receive submitted & show display page
  • 2019-04-28 probably what needs to happen here is that we need to duplicate the logic of whatever calls vcCartDataManager::GetBuyerObject() et al. (currently includes capturing, rendering, and other stuff) and just create the requisite objects, don't try to use them yet.
  • 2019-05-04 The first problem is to figure out how to make sure that this logic gets invoked during the setup events (KI_NODE_EVENT_DO_BUILDING or KI_NODE_EVENT_DO_FIGURING, not sure which is preferable)
    • Seems like it should be happening in vcPageContent_ckout::OnRunCalculations, which does get called.
    • ...but we're trying to receive the form first, here in vcPageContent_ckout::ProcessPage(), before the controls have been created...
    • ...which happens in vcPageContent_ckout::CapturePage, which is called before the input is processed in vcPageContent_ckout::DetectPageRequest() so we know which controls to create.
    • So CapturePage() needs to be split into two parts:
      1. receive raw form data (do not load into controls; just detect request)
      2. load form data into control objects (which must be created first)
    • ...except no, it doesn't; I moved the CapturePage() call so it comes last, and still get the error -- so apparently the controls are not being created wherever I thought they were (where was that again?)
• receive submitted page - $this->CapturePage($oRes);
• process submitted page

To examine -- how do the following functions intersect with the above steps?:

• $this->CapturePage($oRes);
• $this->HandlePageRequest();
