after a mutation my app state (shown in {:inspect-data true}) becomes {nil old-app-state} then {nil {nil old-app-state}} etc. How do I find the problem? The app seems to work normally, no error found in console...

never mind, I passed the wrong ident to fs/entity->pristine*

Is there a story in Fulcro for "offline first"? I believe the client side transactions are optimistic anyway, so it seems like deferred server sync might not b e much of a stretch?

@chancykennedy there are pessimistic transactions for that

I was just reading some Github issues around ptransact. Thanks for the link!
