Vim-go: Method auto-completion PANICs on Golang v1.7

[kontsevoy]

Actual behavior

Updated Golang from v1.6 to v1.7
Tried to auto-complete a structure by pressing Ctrl+X-O and it inserts the word PANIC.

Attaching screenshot:

Expected behavior

A dropdown with the list of req's fields/methods.

Steps to reproduce:

Just a default installation of vim-go will do.

How about restarting your gocode process?

[kontsevoy]

Bam! Worked.

@suzuken @kontsevoy
Sorry, am a golang/vim-go/gocode newbie. How do you restart gocode?
I installed go1.7, vim-go and YouCompleteMe.

[andrewstuart]

Are you sure that's not just the new Request.PANIC method added in go1.7? :wink:

I've also fixed this with :GoUpdateBinaries while playing with the go1.7 beta, in case it crops up again.

For anyone facing this issue in the feature, please run gocode close, reinstall gocode from scratch and then try autocompletion (you do need to start gocode yourself, it is automatically started).
