[flexcoders] Re: Cairngorm 2.2 incompatible with AS-based ServiceLocator?
Hi Ali, Sorry its taken me so long to respond- had to finish up a project. Anyhow, I was able to solve the mystery pretty quickly once I revisited things this morning. I followed your advice and examined the output of describeType(), which led me to discover that the web services properties were made bindable in the MXML based ServiceLocator subclass, but not in the AS based one. This resulted in the web service properties being defined in variable nodes in describeType() rather than accessor nodes. Marking the properties [Bindable] in my AS-based class allows things to work properly, but I still have a couple of question marks about this. How/why do the services get marked bindable in the MXML-based ServiceLocator? What change in Caingorm 2.2 necessitates explicitly marking AS-based services as [Bindable]?

Hi Alistair, _webServices is empty, but we already knew that. Looking at ServiceLocator in the debugger shows all of my WebService objects properly constructed and present, they're just not registered for whatever reason.
