One other thing that caused me frustration in JSF was wanting to reuse a
screen from two different locations. For instance, if I wanted to go to a
customer search screen from orderentry.jsp and custmaint.jsp. There isn't a
way out of the box that allows me to handoff control to the screen higher in
the "call stack" when the user exits the customer search, and instead I
either need to write my own plumbing or created two different screens.

And we've talked about this several times: this isn't a frameworks issue, this is a web application issue. There is no "stack" in the browser, other than one you would implement yourself. The stateless nature of the initial browser and the fact that there is no concept of "exiting" an application is the underlying cause of that problem.

But as you say, it can be done, and in EGL it would be no more difficult than putting a stack in the session and forwarding to the appropriate URL when finished. The more difficult part is remembering state on each page, but that's a different discussion for a different day.
