at a loss here - invitable & confirmable

[syllogismus]

i am using devise inevitable & confirmable. confirmation email & invite emails are working, but it seems like something goes wrong after accepting the invite token. after accepting, it redirects to NEW Password (ok), then it goes to login (flashing: "You have a pending invitation, accept it to finish creating your account. " ), which is wrong, because session came tru accepting link in invite email.
here is my goal:
normal signup works just fine. but for invite, i want no cornfirmation, just accept invite link / token and get new pwd page, than login. no extra confirmation.
steps?

Thx

confirmable and invitable don't play well together when the invite hasn't been accepted yet, see this issue for more details
