You are not making your properties abstract; you are therefore having problems because user data is stored in properties of pages (stored within the page pool), not within the HttpSession as they should be.
When the pages are culled from the page pool, you lose your server side data. You MUST use abstract accessor methods and mark the properties as persistent. Only in this way will properties be stored into the HttpSession. This can be done in 3.0 using XML and in 4.0 using annotations (or XML). The fact that your application works at all in development is a feature. It will neither scale to more users on a single server, or work in properly in a cluster. Not a single example piece of code in TiA or in the Quick Start tutorial tries to do such an "end run" around Tapestry. Do so at your own peril. The only times I don't use abstract properties is when I want to cache an expensive object that is not client- or request- dependent. For example, I may cache an IPropertySelection model, lazily creating it as necessary.
