Subject Re: Flex 5 UIComponent - Behavior Pattern

Alex, you say the prototype was not faster, I suppose this is the case when
all features are enabled which is actually a good result (if it's not
slower). But the idea is that applications almost never require all

Regarding backward-compatibility, if it will prevent innovation, what about
working on a new version that is not backward-compatible in parallel to the
standard version? Existent applications continue to use the standard
version which will be maintained with bug fixes and perhaps also some new
features and when the newer version is out, let's say Apache Flex X (for
10), new applications will use it and old applications can be ported (but
not required).
