Keep getting debug.LogError when hide/reload DcokExample objects group #63

Closed Ericbing closed 4 years ago

debug.LogError : "AssertionException: Assertion failure. Value was Null Expected: Value was not Null When a dockable is docked, its dockedPosition must be valid. UnityEngine.Assertions.Assert.Fail (System.String message, System.String userMessage) (at <23a7799da2e941b88c6db790c607d655>:0) UnityEngine.Assertions.Assert.IsNotNull (UnityEngine.Object value, System.String message) (at <23a7799da2e941b88c6db790c607d655>:0) UnityEngine.Assertions.Assert.IsNotNull[T] (T value, System.String message) (at <23a7799da2e941b88c6db790c607d655>:0) Microsoft.MixedReality.Toolkit.Experimental.UI.Dockable.Update () (at Assets/MRTK/SDK/Experimental/Dock/Dockable.cs:133)"

Way to recreate the issue:

  1. Add two buttons in MRTK-Quest_2.4_Extra scene. Button one: Hide the DockExample object group in Hierarchy panel with "GameObject.SetActive" value=off. Button two: Show the DockExample object group in Hierarchy panel with "GameObject.SetActive" value=on.

  2. Click button one to hide the DockExample object group, then click button two to show the group, then the debug.LogError will keep coming.

Hi thanks for logging this issue! I think you should file it under the official MRTK repo however. I don’t maintain the code in the framework, only the Quest compatibility layer.
