Flex: Cannot tab between controls on a modal popup

Question

Steps to reproduce:

1. Create a modal popup to popup with popupmanager (mine is a group with a skinnable container inside of it)
2. Put field components (textinputs) on the modal popup
3. Attempt to tab between controls

Tab switches to controls behind the modal-popup and ignores the fact that the modal is there. The tab loop only contains controls behind the modal.

I've tried everything from setting tabChildren, to hasFocusableChildren. I can't implement IFocusManager as it's Halo and my modal is a Spark group, but would that work in some capacity? It really seems like Flex just ignores the modal in its focusmanager.

Solution can be found here (if you want to use a Group):

Answer 2

This is not a bug, I'm assuming it's by design.

Group is supposed to be a lightweight container -- just for grouping things together. Group does not implement the IFocusManagerContainer interface.

SkinnableContainer (or more correctly SkinnableContainerBase) implements that interface, and that's why tabbing works when you use it w/PopupManager.

Answer 3

Can you try using TitleWindow instead of group with a skinnable container? We use TitleWindow all the time and it does tab correctly.
