I did as you said, and have the unit tests, and read the wiki on chaining
models... something still isn't clicking though. BTW, I have Wicket in
action and it is fantastic, perhaps there is still something elduing me
though... I still can't wrap my head around why that property model doesn't
update in the first case you show me. If the property model is calling that
object, and doing a get description each time it's called it's own
getObject() method, why doesn't changing the reference externally work?
If you simply point me to a page number and tell me to read until I
understand, I would be greatful!
Thanks again!
