Description

Steps to reproduce:
1. Compile and run attached MXML file.
2. Click the UpperCase and LowerCase buttons for the LinkBar control and List control.

Actual Results:
Setting the labelFunction property on the LinkBar control at runtime has no effect, whereas setting the labelFunction on the List control does.

Expected Results:
Setting the labelFunction property at runtime should cause the LinkBar control to invalidate and redraw its labels.

Workaround (if any):
set the labelFunction property at runtime and then reset the dataProvider (which can be ugly AND expensive).
