Tab key navigation does not work in HAccordion / VAccordion.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run the attached application (testApplication.mxml).

2. On the first tab (flexlib.containers.HAccordion), the tab key does not 
function properly.  Press the tab key from any of the form fields, and focus 
will shift to the TabNavigator.

3. The second tab (flexlib.containers.VAccordion) exhibits the same behavior.

4. The third tab (mx.containers.Accordion) behaves as expected.

What is the expected output? 

Focus should move from form field to form field.

What do you see instead?

In the flexlib accordions, focus shifts to the parent component, rather than to 
the next child component.

Please use labels and text to provide additional information.

This file was compiled in Flash Builder 4 (build 272416), and the HTML file was 
served by Tomcat (version 6.0).  The same behaviors are exhibited in both 
Mozilla Firefox (version 3.6.8) and Google Chrome (version 5.0.375.127).

I am in the process of converting a project from Flex 3 to Flash 4.  These 
behaviors were not exhibited in the previous version of flexlib that was 
compatible with Flex 3.

There is a workaround for this issue.  The hasFocusableChildren property should 
be set to true.  If you're running a local copy of flexlib, you can add this 
right to the HAccordion class.  If you're just using the swc, you'll need to 
set this property at runtime (either in the MXML tag for the accordion or with 
ActionScript).  Many, many thanks to Doug McCune for pointing this out!
