For example in this piece of code the frame ends up containing component one to right and another to left though I'm adding both the component to right.

Yeah, logically it is behaving right. But is it ok if component Orientation affect/creates confusion with the functionality? Say when user adds a component to left pane, set orientation to RIGHT_TO_LEFT and then removes left component which would actually remove right one sine its been oriented to right?
