I came across another incident of Cairngorm throwing a stack overflow error.
I had a Cairngorm ModelLocator named AppModelLocator (my subclass). In it, I
declared a class variable that instantiated another class like so:
public var currentProfile : MemberProfile = new MemberProfile();
And in the MemberProfile.as class, I create a reference back to the model:
private var model :AppModelLocator = AppModelLocator.getInstance();
What this did is create an infinitely recursive loop I guess, because
AppModelLocator.as creates an instance of MemberProfile so it would try to
get an instance of itself which would instantiate MemberProfile again, ad
infinitum.
So, in AppModelLocator.as, I changed
public var currentProfile : MemberProfile = new MemberProfile();
to
public var currentProfile : MemberProfile;
And in the constructor I assigned it:
currentProfile = new MemberProfile(modelLocator);
// not shown: modelLocator is the private static var modelLocator
:AppModelLocator, standard Cairngorm usage
I still had to pass modelLocator as a parameter to MemberProfile() to avoid
using AppModelLocator.getInstance within, which would cause the inifnite
loop.
Then in MemberProfile.as:
private var model :AppModelLocator;
public function MemberProfile( modelLocator :AppModelLocator)
{
model = modelLocator;
}
So the bottom line:
You cannot use the `private var model :AppModelLocator =
AppModelLocator.getInstance();` convention of creating a reference to your
model inside of a class that is instantiated WITHIN the model!! It causes an
infinite loop. Instead do it as I describe above.
