[flexcoders] Re: first user tab is slow

[schneiderjim]

We will run the profiler to see. We have a very large, form based app, so there 
may be something there. It can sometimes take up to 3 - 4 seconds to tab to the 
second form field. 

Some questions:

1. When is the sorted list computed? On the first tab?

2. Is there any way we can change when that happens?

3. What determines whether an object can receive focus? If we have a 
form/canvas over a form/canvas over ... is it only the visible form that has 
objects that can receive focus?

4. What do you mean by startup time delays? Loading the swf?

 expect you'd be having startup time delays that would be even more 
 problematic.

 In our app, we experience a significant delay when the user tabs from the 
 first form field to the second. After that, tabs work as expected. Is there a 
 reason for this? Is there a way to eliminate this delay? I'm not sure whether 
 this is a factor, but many (not all) of the forms are dynamically created (in 
 AS).
 
 Thanks

Make sure you have not been using creationPolicy=all.
