Omnicomplete uses stale completion list

[ackalker]

Problem: Omnicomplete after <identifier>. sometimes shows stale completions (from a previous omnicomplete). Seen with:

$ vim --version | head -n 3

Steps to reproduce:

• In an empty directory, do:

$ npm install cheerio

• Create files with these contents:

.tern-project:

{
  "plugins": {
    "node": { }
  }
}

example.js:

cheerio = require('cheerio');

Now, edit the example.js file with Vim:

• Add a line: cheerio. and start omni complete (C-X C-O) after the .. Observe the results are correct.
• Without closing omni complete (i.e. don't hit Escape), hit Backspace a few times to remove cheerio. then type console. then start omnicomplete again. Observe the completion results are for cheerio., not for console..

Workaround: always accept a completion, even if it's just temporary:

To make sure that omni completion doesn't get 'stuck' on a particular identifier, always accept something from the omnicomplete window. If it's a function, add an empty pair of parentheses (important!), then add a semicolon (perhaps not required, but it works) and press Enter.

This appears to 'reset' the omni completion so that next time it will complete on the right identifier. The temporary completion can now be deleted.

Wow, that was fast! Thanks :-)
