RE: [flexcoders] what's going on with this Flex?!?

[Gordon Smith]

The behavior you're seeing is the Deferred Instantiation feature of Flex. The point of it is to avoid creating components until the user can see them, in order to minimize the application startup time.   Setting creationPolicy="all" 'fixes' the problem by disabling this feature. It is almost never the right thing to do, as it causes your app to start up more slowly. You should instead write your app in a way that works with Deferred Instantiation.   Instead of trying to push data into a TextInput before it exists, store the data in a var and then have teh TextInput "pull" the data into itself in its 'initialize' handler, which is guarantee to execute when the TextInput gets created.   - Gordon   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Matt Horn Sent: Thursday, September 14, 2006 7:15 AM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] what's going on with this Flex?!?   if that is the issue, you could set the container's creationPolicy to all.
