Vim insert-mode completion ends on typing backslash

Question

I have a problem with vim's tag completion feature for php namespaces. Every time I type backslash, vim's completion popup goes away (even with iskeyword+=\\).

Let's say we have next class in our project:

Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle

After every backslash I have to type "C-x C-]" to get my completion popup back on the screen. That's very annoying and really pisses me off.

Could someone explain why this happens and maybe suggest some workaround?

Vim doesn't do automatic completion: the completion shortcut has to be typed again and again if you want multiple consecutive completions. You can see the principle at play when doing filename completion.

You should try one of the few autocompletion plugins available: neocomplete, autocomplpop, ycm...
