    Hi

    I discover this amazing package but I have some trouble to use it.
    I imported package v0.11.1
    I Configured Localization settings with 'fr' and 'en' language.

    I added a UI_TEST table with a key 'LANGUAGE'
    upload_2021-5-2_23-38-57.png

    added a component 'Localize string event'
    upload_2021-5-2_23-41-0.png

    I always have this error message

    Code (CSharp):
    1. NullReferenceException: Object reference not set to an instance of an object
    2. UnityEngine.Localization.Settings.LocalizedDatabase`2[TTable,TEntry].OnLocaleChanged (UnityEngine.Localization.Locale locale) (at Library/PackageCache/com.unity.localization@0.11.1-preview/Runtime/Settings/Database/LocalizedDatabase.cs:418)
    3. UnityEngine.Localization.Settings.LocalizedDatabase`2[TTable,TEntry].ResetState () (at Library/PackageCache/com.unity.localization@0.11.1-preview/Runtime/Settings/Database/LocalizedDatabase.cs:445)

    Hi,
    This looks like a bug. I had a go at reproducing it but could not.
    What version of Unity are you using?
    It looks familiar to an old bug with SerializeReference. This was fixed some time ago though. It may be worth updating to the latest patch release of the version you are using.

    Hi @karl_jones

    I'm using Unity v2020.1.6f1.
    I use all this package in my VR project :

    Another problem, I don't see at runtime the dropdown language list

    Do you mean in the player you don't see it? It's an editor only feature. We include some Samples to show how to do it in the player. You can get to them via the package manager window.

    It's probably related to the original problem you are having. Please file a bug report so I can take a look at your project and understand what has gone wrong.

    Ok I will create a bug report.
    Last detail, I don't know if there is a relation between "Localization" package and "XR Interaction Toolkit" package but as soon as I add Localization, XRRig component doesn't work at all.

    There's no connection between those 2 packages so that's strange, sounds like a bug.

    Hi, I'm having the same problem on Unity 2020.1.3f1

    I've tracked it down to LocalizedDatabase.cs line 418

    In the foreach loop in OnLocaleChanged, TableOperations is null.

    This shouldn't be possible, since TableOperations is automatically assigned and is read-only.

    This is a brand new, empty project. I've set up one local (en-gb), one Asset Table and one String Table.

    [edit] I've also attached the project to a bug report, and to this reply

    Can you try updating to 2020.3? This is an old bug with serializereference that should be fixed In the latest version.

    Yeah that looks like it's working in 2020.3.6f1

    Case 1333659 can be closed I guess

    Yes, updating unity version to 2020.3 worked for me as well.

    I have the same issue on version 2019.4.3f1. I created new project just to test this package and it worked! And as soon as I changed version to 2019.4.3f it stopped working and same error appeared. The version of Unity I initially tested it on was 2019.4.20f1 - on this version it is working. Unfortunally I cant downgrade my main project to that version, it couses lots of errors.
