Yes, you are correct about that. I keep forgetting that Spark pushes data to the skin parts. > >>I haven't looked at the Alert code, but it sounds like the design may >>not be correct.

And this is sort of why FlexJS uses composition instead of inheritance. There is no good answer in Spark and we often did duplicate code. See the three copies of prompt text handling for example. IMO, you want to hide any APIs that invite the user to add new content to the Alert so you'd have to @exclude various addElement/removeElement APIs if Alert extends SkinnableContainer. Duplication of code is bad but there is precedence for doing it. The choice is yours... -Alex
