Sync System: root object added listener does not raise events properly

I’m just having trouble getting a listener on the root object to raise events properly.

RootSyncObject = SharingStage.Instance.Manager.GetRootSyncObject();
objElementAdapter = new ObjectElementAdapter();
objElementAdapter.ElementAddedEvent += OnElementAdded;
objElementAdapter.ElementDeletedEvent += OnElementDeleted;
RootSyncObject.AddListener(objElementAdapter);

I’m getting the root object and adding a listener but that listener never raises ElementAddedEvent nor ElementDeletedEvent.

Here’s the branch I’ve set up for proper testing: https://github.com/HodgsonSDAS/HoloToolkit-Unity/tree/SyncSystemTests

1. Open SyncSystemTests.unity
2. Add breakpoints to ObjectElementAdapter.cs lines 34, 123, & 137.
3. Start Debugging in visual studio and attach to Unity Editor.
4. Run the SyncSystemTest.unity scene.
5. Create/Delete object object and int elements.
6. Increment and decrement int value.
7. Observe events not raised.

Oh, local changes do not raise events on the local client. Events only get raised by remote client changes. You need to keep any local modifications done to intValueText.text.

D’oh, looks like it was. Pull request makes much more sense! Done. You should see the add/delete event for ObjectElements too, but I didn’t test that. Only investigated the IntElement for you.

Note that for every ObjectElement you need to AddListener to receive that ObjectElement’s events. The change events don’t propagate up to the root.
