nested-stack sample process death state persistence might have gotten messed up with 1.5.0

[Zhuinden]

It definitely used to work but now the viewstate seems to get cleared.

That's not good at all! The most intrusive change was switching to DefaultStateChanger, so that's the primary culprit.

Nested stacks are so hacky.

Oh it's because the retained fragment is restored after the scopes are reset, so the backstack manager is still nulled out at the time.

I guess the navigator switch killed it just gotta switch the two lines.

.... Actually, I think the PreserveTreeScopeStrategy doesn't have all the keys after process death yet... A different strategy is required that keeps track of all keys in all active stacks...

[Zhuinden]

......man, this is disappointing. I'll fix this when I figure it out correctly.

[Zhuinden]

Honestly, I should probably rewrite it.

Didn't feel like it yet. Gonna happen eventually tho.

I'll leave this for another day, another time, another place, and another solution.

Deleted sample.
