composite components and focus delegation

[Jason Guild]

Hi all:

I have a reusable component that consists of many TextInputs that make 
up a mailing address form. When I use this component inside of a popup 
dialog I want to give focus to the first focusable component within the 
address form.

What is the best way to do this in the dialog so that I don't have to 
hardcode setFocus() on any of the particular fields within the address 
form? Does the address form component implement IFocusManagerComponent? 
If so, what is the recommended way of delegating focus within the 
address form
component? Do I override UIComponent.focusInHandler() in the composite 
component and call setFocus() on one of the child TextInputs?

Ideally, in my dialog I would simply call addrForm.setFocus() when it is 
shown and the address form would decide which of the sub-components 
should receive the focus. Any help on gotchas or other details I need to 
account for are greatly appreciated.

Thanks,
Jason
