Hi You need to type cast the object/component to DisplayObject
Just keep in mind: any container you want to add any object just typecast to DisplayObject(); i.e Here mainGrpHolder is some kind of holder container i.e canvas, VBox, HBox var gObj: ColumnChart = new ColumnChart (); mainGrpHolder.addChildAt(DisplayObject(gObj),i); or mainGrpHolder.addChild(DisplayObject(gObj)); For using any properties for component/object added use: reverse the type-cast . gObj = ColumnChart (mainGrpHolder.getChildAt(i)); trace(gObj.PropertName); trace(gObj.methodName()); This works very fine,I used it.

So if you add the Text object directly to the Canvas, it works, but, if there's a UIComponent in between, it doesn't. Canvas => UIComponent => Text // doesn't work Canvas => Text // works Suggestions: 1) Check question.parent.parent ... is it pointing to the Canvas? 2) Compile with -debug and see if you're getting a runtime error (and see the stack trace) 3) Are you overriding measure() in your UIComponent? If not, at least set its width and height explicitly.
