Flex 4.5 - Custom NativeWindow and problems - apache-flex

Question

I have a class FlexNativeWindow who extends to NativeWindow.
I use this method to create new window on my AIR app.
All works well but some keyboard interraction is not availaible.
For exemple focus arround textinput is not visible.
Key down and up don't work on DropDownList.
TabOrder doesn't work well!
Can you explain Why? Because I'm very desapointed!
Code to create the new window
var wdetcorr:wDetailCorrespondant = new wDetailCorrespondant();
wdetcorr.monIdCorresp = correspDG.selectedItem.crIndex;
var wOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
wOptions.systemChrome = NativeWindowSystemChrome.NONE;
wOptions.transparent = false;
var fnwDetailPatient:FlexNativeWindow = new FlexNativeWindow(wdetcorr, wOptions);
fnwDetailPatient.active();

You should implement IFocusManagerContainer in FlexNativeWindow to fix the focus issues.
Here is how to do it in Flash Builder:
Press Ctrl + Shift + T and type in IFocusManagerContainer
Open corresponding file
Implement all declared methods in your class FlexNativeWindow
P.S: However this approach can fail because flex components should be placed inside flex container while NativeWindow is a native class, not a Flex SDK class. I suggest you to use Window class that is a Flex container and already implements IFocusManagerContainer.
