How to identify object instances (StableObjectId)?

Hi 
IIRIC, in Flex/AS3 each object is identified by a unique id, something like
MyClass@aa77fdre7ee.

I need to identify a certain object instance while debugging a Royale app
but didn't find this kind of identifier.

Instead, I found this:

[[StableObjectId]]:35

Is this the pendant to the object id which I described above?
IOW: 
When I want to make sure that I am working with the right instance of an
object, is this StableObjectId a proper way to trace this?

Thanks,
Olaf

That’s my understanding too.

Thanks, Yishay... it really seems that StableObjectId is coming from Chrome.

Just to make sure that I got it right:
What if we create a couple of instances of the same class, all objects are
in the same initial state, all objects are total equal e.g.:

var instance1:MySuperComponent = new MySuperComponent();
var instance2:MySuperComponent = new MySuperComponent();
var instance3:MySuperComponent = new MySuperComponent();

In Flex, the object id can be used to distinguish between those objects out
of the box.
Is my understanding right that in Royale, we have to modify or add an object
property (e.g UUID) of/to each particular object in order to be able to
distinguish between all instances.

Thanks,
Olaf

Hi Olaf,

As soon as you say a scenario is rare, then it definitely shouldn't be baked into the base classes for PAYG reasons.

It occurs to me that for any component that implements IStrand (like UIBase), you could define a bead that goes on the strand that would generate an identifier. Or document the pattern that folks could use to add an identifier to a subclass of an existing bead (so you can swap out a bead instead of having to alter the app to inject an additional bead). Maybe you can write that up and contribute it.

Even if these scenarios are probably rare:
One scenario is to display multiple instances of the same UI component at
the same time. After initialization, they are all identical.
Another scenario is when you create whatever other object instances
dynamically at runtime it could occur, that you accidentally created more
instances than needed (without knowing about this issue). With a unique

For PAYG reasons, identifiers are not added to every object "just-in-case".  If you need them, add them.

I'd be interested in understanding the scenario where you create multiple instances with the exact same set of properties.  I would think it would be better to share one instance in that case.

It should be simple to add uid's where you need them unless I'm missing something:

Import org.apache.royale.utils.UIDUtil;
...
   Private var _uid:String;
   Public function MyConstructor(){
      _uid = UIDUtil(this);
   }

In Intelij debugger there is unique number for each instance. I can see
this during debugging, so maybe it's a matter of support from IDE sight. It
is very helpful when you wanted to compare instance of some object in one
place of app with another place.

Hi Olaf,

This is how it looks like in intellij [1] - Each object has such unique
number. If it's the same instance of object you will have the same number
in other place of applications.

Not sure exactly where it’s manufactured but it looks [1] like StableObjectID id a property created by Chrome. I guess, use at your own risk.

I've never seen that.

For PAYG reasons, fewer objects are assigned ids just in case in Royale.

For debugging, you might be able to call UIDUtil on the objects to assign then a UID.  But often in the debugger you can identify an object by the properties it has and its parent.
