Unreal Engine 4 is available for Win10 UWP app dev now

[anonymous_user_537a337d]

StatisticManager::SetStatisticIntegerData throws a “User not found in local map” exception:

The code is fairly straightforward:

bool FOnlineLeaderboardsLive::WriteLeaderboards(const FName& SessionName, const FUniqueNetId& PlayerId, FOnlineLeaderboardWrite& WriteObject)
{
	UNREFERENCED_PARAMETER(SessionName);

    if (!LiveSubsystem)
        return false;

    const FOnlineIdentityLivePtr Identity = LiveSubsystem->GetIdentityLive();
    if (!Identity.IsValid())
        return false;

    const FUniqueNetIdLive UserLive(PlayerId);
    Windows::Xbox::System::User^ XBoxUser = Identity->GetUserForUniqueNetId(UserLive);

    Microsoft::Xbox::Services::XboxLiveContext^ LiveContext = LiveSubsystem->GetLiveContext(XBoxUser);
    if (LiveContext == nullptr)
        return false;

    Microsoft::Xbox::Services::Statistics::Manager::StatisticManager^ mgr = Microsoft::Xbox::Services::Statistics::Manager::StatisticManager::SingletonInstance;
    if (mgr != nullptr)
    {
        for (FStatPropertyArray::TConstIterator item(WriteObject.Properties); item; ++item)
        {
            Platform::String^ itemName = ref new Platform::String(*item->Key.GetPlainNameString());

            int32 itemValue;
            item->Value.GetValue(itemValue);

            long long llValue;
            llValue = itemValue;

            mgr->SetStatisticIntegerData(LiveContext->User, itemName, llValue);
        }

        mgr->RequestFlushToService(LiveContext->User);

        return true;
    }

	return false;
}

Am I using the call to GetLiveContext with the user correctly?
I’ve also tried using LiveSubsystem->GetDefaultLiveContext() but that didn’t work either.

Any help is appreciated.
