Alright tested several things here:
1. Doing it my way does not render any of the Form layout stuff, even when I set a height of 500 on the Window (which should be plenty of height). I had to remove AutoHeight.
2. Doing it Geoffrey's way. I added a height of 500 and it worked, with rendering of objects.
So I have to point out two things. First, the AutoHeight doesn't work in either case. For this login window, we need to have AutoHeight set, because we will have buttons and options available to certain people coming from different web pages. We don't even want a space for "hidden" objects if they don't have access to them (we don't even want one login web page to know those options even exist for another login page). This worked fine in pre-1.0.
Second, objects in the FormPanel don't even render for #1. The window, itself, renders just fine. The FormPanel objects and Anchor objects do not.
Let me point out that BEFORE v1.0, this login page was working exactly like we wanted it. In v1.0, the page isn't anywhere near what we need or want (because of rendering).
Let me point out as well, that before I did the refactoring that Geoffrey suggested all I did to this page was change the <Body> tag to <Content> for the Window and for all Panels and then encapsulate the FormPanel's FormLayout in an <Items> collection, as required. According to what Geoffrey said in an early post that adding the <Items> collection shouldn't really have changed anything since it was "already" (in a way) required it just wasn't enforced.
So, having just made this minor changes to the page, why would it have such a drastic effect on rendering and formatting?
