Yes binding will generate the "objectChange" when it's done automatically, but you'd need to look at the details to figure out if it's the right property for you. Generally if you find yourself wanting to handle the event it's a good idea to do the re-write yourself because I think it's clearer what you intend to accomplish rather than relying on code-gen.

I have digged a little into the generated AS and apparently the "objectChange" event is used in general... but Is there a more granular approach? As a tangent to this issue.. ( now this is just in case any cairngorm fella is reading this ), I believe that the ModelLocator should be wrapp'able as an MXML tag to support inline event handlers... I always do that with my model locators ( I just call them models though ). Of course the MXML wrapper would create a new instance, which itself would be wrapping a singleton. there are some patterns around that ( all of which involve some unwanted boiler plate code and repetition ). I will post some more on this later perhaps. need some sleep now. good night ;) Best, Aldo -- ::::: Aldo Bucchi ::::: mobile (56) 8 429 8300 -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
