Hi Dimitros,
thx for the feedback. Things are more clear now.
Just another question: How would you handle the same situation in a
Flash application? Would it be a good idea to let the Forms/Views
register with the ModelLocator for changes in the model? Or does that
give the ModelLocator too much responsibility.
I see how the binding is done automaticly by Flex and that rocks...if
only Flash could do that in such an easy way.
regards,
Christophe
