Binding the old way

[nishantkyal]

Hey,

I've a few models which I'm injecting as singletons using smartypants

In application.mxml
injector.newRule().whenAskedFor(SessionVars).useSingleton()

In a class called TestClass --

[Inject] public var sessionVars:SessionVars;
public function TestClass() {

SmatyPants.injectInto(this);
BindingUtils.bindSetter(sessionUpdated, sessionVars, someVar);
}
private function sessionUpdated(someVar:String):void {}

My method sessionUpdated is not called when someVar is changed.

Is there a way to call a method using live rules whenever a property
of an injected object changes?

Hope I explained my situation clearly enough.

A couple of things to check:

1) SessionVars has [Bindable] fields
2) Make sure your BindingUtils.bindSetter() call uses a String for the chain parameter. If you want to bind to foo.bar, use BindingUtils.bindSetter(myFunction, foo, "bar"). To bind to foo.bar.baz, use BindingUtils.bindSetter(myFunction, foo, ["bar","baz"])

Thanks. The mistake was in the creation sequence. The injection
container hadn't been initialized since I put it in the
creationComplete of the app and TestClass got created sooner. :-)
