Thank you Alex, it resolved the problem. In addition to what you
mentioned, I also assigned tabChildren and tabEnabled for child
UIComponents.
e.g.
private var childContainer:UIComponent
override .... createChildren()...
{
childContainer = new UIComponent
childContainer.tabChildren = true
childContainer.tabEnabled = false
childContainer.addChild(some UI Component...)
addChild(childContainer)
}
Thanks again for your help Alex.
Although I have one doubt :) it is related to term "Container".
IMO: Container is a class which extends UIComponent and implements
IContainer interface. Developer will use "Container Component" to add
children. In my case I am not implementing IContainer then how it is a
container. Could you please explain a bit more.

not implement IFocusManagerContainer, but set tabChildren=true and
tabEnabled=false in the constructor of your subclass then try it and
let us know if you have further questions.
