Hi did not go throgh your code but the problem is that you get your data on app creationComplete. By the time you have the data the poanel is not created yet. That is why you get the error. I don't know what are you trying to accomplish and why are you loading another swf in the main app. My suggestion is to restructure you code a little bit MVC style. Get the data into a model, put a variable currentPlanType and wit respect to that bind to you current selected plan. It will work with binding as you already said, because the bindings fire first when null and secionnd time after you get your data and have the component created. You keep duplicated code in createBreakfast , Luynch and dinner which is not OK.
