showDialogFragment: fragment that does not belong to this FragmentManager!

[solareye]

I have FragNavController in my activity. When I call showDialogFragment like fun BaseFragment.showDialogFragment( bottomFragment: BottomSheetDialogFragment, requestCode: Int = 0 ) { bottomFragment.setTargetFragment(this, requestCode) this.baseActivity().fragNav?.showDialogFragment(bottomFragment) } app crashed with

fragment that does not belong to this FragmentManager!

Reproduced same (or similar issue?) with these steps:

1. Open fragment A
2. Open fragment B on top of A
3. Add a dialog in fragment B
4. Click a button on the dialog dismissing it and pop fragment B as a result
5. Try to add a new dialog - doesn't matter where, the fragment manager is "corrupted" at this point
6. Exception thrown

The way I fixed it - where I pop fragment B, I also added a call to clearDialogFragment BEFORE popping B.

p.s. The Exception I received was:
