Please check SessionFactory->createSessionFromPreKeyBundle() line 74

Hi, var sessionStateList = new SessionStateList((serialisedState) => { return store.putSession(toIdentity, serialisedState); });

you never initialize serialisedState prior to this call. I've been trying to figure out what exactly you are doing here?

I'm passing a callback to the SessionStateList constructor. serialisedState is a parameter passed to the callback. It is called from SessionStateList.js, with a JSON string.

still struggling to follow the logic :(

[joebandenburg]

I wanted to make SessionStateList have a save method (for use by Session), but I didn't want to pass the entire Store interface through to the SessionStateList constructor as it only really needed one method. Instead I pass in a callback that provides only the saving ability. It means the SessionStateList constructor is only passed the minimum dependency it requires.

Perhaps it would be simpler if the SessionStateList constructor is passed the Store and the identity and calls store.putSession itself.

I've changed this quite a lot in the latest version. It's much simpler now. Reopen if you're still having problems :)
