Hi Marco, first up you have to ask yourself why you want this feature? There may be another way to solve the problem. However, here's what I know of your specific question...
Last time I checked (Flex 3 beta 2) there was no *official* way to inspect the bindings on a component at runtime. However, if you create a component with bindings and load it up at runtime, you will find there are undocumented properties that enable you to do this. Look for a "_watchers" array -- you will also find it helpful to keep the generated actionscript that the Flex compiler normally throws away so you can read how databinding is implemented. The properties above are not part of the public API, so could change at any time. In fact, IIRC some of the very binding properties I just mentioned may even have been deprecated in the final Flex 3 release... proceed with caution. Which is why I ask what the actual problem is you are trying to solve -- perhaps the list can help you come up with other ideas :-) For example, your idea of overriding addEventListener is cunning -- perhaps that solution can be explored further.
