Press TAB and wrong tag is inserted

Possible resolution: When pressing TAB a match against the currently entered text should be made.

It's using the highlighted record. While the auto-complete could be made to be a little more intelligent, this certainly isn't a bug. The expected behavior is that if you press tab while a tag is highlighted, it will insert the highlighted tag...which is what this does.

Also, sidenote, I just tried this specific example, and it immediately switched to active-directory as soon as I hit the dash. Hitting tab selected active-directory.

    That's interesting. Which browser are you using?

  • Hmmm I'm on Firefox. Could be a perf issue.

I have this problem periodically when I'm entering tags, but after the question posts, I'm unable to reproduce the issue. Happens with IE7. From time to time, it'll replace the first tag with the one I've tabbed to select. Wish I had more info but it's very sporadic.


The completion lag thing also happens to me (firefox and chromium). It makes that other bug more annoying.
