Rich, I'd love some confirmation of the following if you can, I'm in the process of looking at some issue with the BeanContext and Control use in NetUI and I have a question about threading. I believe that we make the statement that PageFlow are single threaded. The issue is that I believe we in fact allow more than one thread into a page flow. Here is an example of where I think it can happen.
If you have a set of frames on a page, all making requests to the same page flow, they will serialize access to the actions in the page flow. When the first thread finishes the action and forwards to a JSP, the second thread is allowed access to the page flow. This is the reason we say things are single threaded. The problem is that if the JSP takes a while to run and it databinds to properties on the page flow you can have multiple threads running through the page flow. The first thread is calling property getters while rendering the JSP and the second thread is running an action. This is actually not uncommon if the property being accessed calls a control that accesses an external resource like a database. Rich, can you comment on this? Is there something else that prevents multiple threads from entering a page flow?
