"If you add an id to a component created at runtime, that id can't be used as a reference to it.", precisely. It is just a string property of the component and the parent component knows nothing about it.
An id on an mxml tag works as a reference because the compiler creates an instance variable with the name specified in the id property, and assigns a reference to the component instance to it. If you manually addChild(), you need to do the same.

TIA, (1) An array is always equal to itself, no matter how many changes you make to it, so you can't bind to it unless you broadcast change events for it manually. Use an ArrayCollection instead. (2) You already have a reference to tileList. If you add an id to a component created at runtim, that id can't be used as a reference to it. HTH; Amy
