Hi, anyone have issues when using databinding, and viewmodel's with mutable live data objects and fragments? e.g. on device rotate, I get `onCreateView` called twice, and 2nd time, my mutable live data is blank/fresh

onCreateView gets called twice? Where and how are you adding the fragment to the activity?

Its added like:
```
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_three)
        val host = NavHostFragment.create(R.navigation.my_navigation)
        supportFragmentManager
                .beginTransaction()
                .replace(R.id.my_fragment_container, host)
                .setPrimaryNavigationFragment(host)
                .commit()
    }
```

The fragment will stay attached to the activity after rotation. Check if the onCreate gets called the first time and only then add the fragment

Just make the fragment transaction only `if (savedInstanceState == null)`
