Ummmmm actually my example is wrong, i was missing something, let me
explain again:
I have 3 classes as a matter of fact, classes A and B are correct but
i forgot to mention that inside B there is an object C:
[RemoteClass(alias="com.test.B")]
public class B {
public var id:Number;
public var name:String;
public var myC:C
}
[RemoteClass(alias="com.test.C")]
public class C {
public var testVar1:Number;
public var testVar2:String;
}
A objectA = new A();
objectA.myMap = new HashMap();
B objectB1 = new B();
C objectC1 = new C();
objectB1.id = 1;
objectB1.name = "Test";
objectC1.testVar1 = 2;
objectC1.testVar2 = "Hello";
objectB1.myC = objectC1;
myMap.put("key1", objectB1);
Now here is the deal, the only property being reset is the C object,
the id and name properties are not reset
for each(var i:* in objectA.myMap) {
if (i is B) {
trace(i.id + " " + i.name);
trace(i.myC.testVar1 + " " + i.myC.testVar2);
}
}
The first trace works fine, but the second trace shows NaN and empty
string.
If i change the code to:
for each(var i:* in objectA.myMap) {
if (!(i is A)) {
trace(i.id + " " + i.name);
trace(i.myC.testVar1 + " " + i.myC.testVar2);
}
}
Both traces work fine, prints 1 Test and 2 Hello.
Like you said i have some logic inside the B constructor:
public function B() {
myC = new C();
}
I commented the constructor and instead of getting the values reset i
got an error saying i tried to access a null reference, since C is
null (if i don't use an instance of B then it works fine).
So i am kinda back where i started, when i use the B class the C
object inside each B object is reset.
