For expressions like "x.y" and "x.z" Stripes will call getX() to get the "x"
property of your ActionBean. If getX() returns null, then it will
instantiate a new instance and call setX(newThing). Then it will call
setY(..) on the new instance. When it evaluates the next expression ("x.z")
it will call getX() again. If it gets null that time, then it will create
*another* instance and call setX(newerThing) and then call setZ(..) on that
instance.
In short: make sure that if setX(..) is called then getX() will return
whatever value was passed to the setter. Or if getX() never returns null,
then make sure it returns the same reference every time it is called. A
getter that returns two different references on sequential calls would
result in the behavior you're seeing.
