Yeah, I could definitely do that... I was more interested in doing things the "right" way, at least in line with convention, and my impression of the convention (from the docs on writing AS components) was that overriding commit properties was the thing to do. Of course, none of the examples address a derived component updating an internal property, so maybe this scenario warrants a different convention... but it didn't seem too far off the beaten path. Calling super.commitProperties() at the end of my commitProperties() does the trick. It still feels like I'm working around a potential problem in the framework, though, or at least my weak understanding of that part of the framework. Troy.
