Sorry for the vauge subject... here's what I'm trying to do that does not work.
I am creating a MainApp class instance in my mxml project file. I want to use this to control the basic common stuff throughout the application, and I have made an instance of a Canvas object that I will be using as a container to the constantly changing part of the screen. I made a ContentTemplate class that extends UIComponent (I had problems with addChild in actionscript before I realized if it's not pure as3 it needs to be a UIComponent to work). From this ContentTemplate class, I have created several classes that extend it and want to use addChild/removeChild to change that canvas part of the program. So, in MainApp I have a variable contentScreen of type ContentTemplate. Lets just say all ContentTemplate is doing is making a new text control. I tried to make this text control in the ContentTemplate, and since it is extending UIComponent - I thought just a this.addChild would work... Then in mainApp just add it to the display list of the Canvas object. This does not work. If I pass a reference to that canvas object in the constructor, then addChild from there it works. Hopefully I somewhat clear what I'm trying to do - and anyone have any suggestions why this would not work? Thanks for any response, Jason
