I think you are getting confused by comparing flex
development with jsp serverside development, its completely
1. How to pass hidden variables using flex.(In jsp we pass it
throuth hidden field, is there any mechanism similar to that one)
-- honestly, where do you really want to pass hidden field to
? (hidden fields is a hack implemented to overcome the way http
protocol works , in flex you don't need that hack) .
2) you can implement exception routine same way (even easier
in flex) if error occures show this and this page(for example error
canvas. with error mesage thats it,
3) How to do session handling in Flex.
-- question is too vague, do you ave concrete problem that
you think of?
