Thanks very much!

Im down to solve this one if @ciwolsey doesn't want to

[ciwolsey]

Added a fix that greens the test too but I'm definitely not sure I've done it in the best way.

[abhiaiyer91]

why was this removed?

[stubailo]

The problem we're trying to fix here is that calling refetch currently kills polling completely, but that's not the intended outcome - ideally the client will keep polling after the forced refetch.

@ciwolsey I think this does what we need, but the linter checks are not passing. Can you look into that?

@ciwolsey Any update on this? It seems the only thing that you'd have to fix is this:

test/QueryManager.ts[753, 9]: if statements must be braced

[ciwolsey]

@helfer Fixed the if statement

@ciwolsey Thanks a lot! Could you do a rebase as well? We've merged some other PRs into master since you made this one.

[helfer]

Merged! Thanks a lot!
