Changes in Flex4beta state syntax

Flex4beta upgrades state functionality to a comprehensive MXML language feature. As a result, you may find states more flexible and straightforward. The new state syntax is more inline, allowing state-specific changes to be specified in context. Here are the main differences in Flex4beta syntax:

Only states are defined in the state array.

Add Child and Remove Child are not allowed in the new state syntax. You must use the includeIn and excludeFrom attributes on a component to define the component's role in a particular state.

In the following Flex3 example, the state contains a Button and deletes a TextInput only if the document's currentState is submitState. For more complex states, this approach can be very detailed.
