Stuck trying to read the global light angles (Cannot identify key type)

[Heimdaal]

// Place the enumeration into the document descriptor
var document = sTID("document");
var ordinal = sTID("ordinal");
var target = sTID("targetEnum");
var ref = new ActionReference(); 
ref.putEnumerated(sTID("layer"), sTID("ordinal"), sTID("targetEnum")); 
var desc = executeActionGet(ref);
var keyID = desc.getKey(11);
alert(typeIDToStringID(keyID));

I've tried all sorts of methods on this key and I don't know what to do with it. IE: How do you go into it deeper when you can't even find out what TYPE it is?

desc.getBpolean(keyID); // returns true

desc.getDouble(keyID); // returns 3

desc.getInteger(keyID); // returns 3

desc.getList(keyID); // returns an ActionList -object containing nothing

desc.getType(keyID); // returns INTEGERTYPE (because duh... the key is a number)

desc.getUnitDoubleType(keyID); // returns a new keyID for noneType

desc.getUnitDoubleValue(keyID); // returns 3

TL:DR:

Where is the global light - altitude angle, stored? How do I retrieve it?

alert(globalAngle());

function globalAngle(){

var ref = new ActionReference();

ref.putProperty(charIDToTypeID('Prpr'),stringIDToTypeID("globalAngle"));

ref.putEnumerated( charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") );

var desc = executeActionGet(ref).getObjectValue(stringIDToTypeID("globalAngle"));

return desc.getDouble(stringIDToTypeID("globalLightingAngle"));

};
