Flex - Checking for change in fields under a tab?

Answer to question 1 is as follows; Use a Boolean variable to track if a user has edited data. When the user selects a tab set this variable to false. Listen for the change event on all fields within the tab.

Set the change event handler for all fields to be a method which sets the Boolean to true. For the dynamic fields, add the same change event handler that the other fields have. Do this as soon as you create each dynamic field.

See the code below.

For 1) you could dispatch an Event every time a user edits a field. The event can be handled by a command which will update some properties in your model with the right info about what got updated. Then whoever cares in your view can bind to those properties.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
