In Firefox I receive I is undefined in the Error console. In Opera I get a more elaborate message including a stacktrace:

Uncaught exception: TypeError: Cannot convert 'I' to object

While asking a question, to receive this error, all you have to do is:

  • Type anything in "Tags" when asking a question, hit Tab or Enter to select
  • Type " " (space) to get the suggestion list again
  • Type anything that can be selected and try to select
  • BOOM! error as above in any browser

If you don't look at the error console, nothing happens: the selected tag will not be added to the list of tags.

This question appears to be off-topic. The users who voted to close gave this specific reason:

  • "The problem described here can no longer be reproduced. Changes to the system or to the circumstances affecting the asker have rendered it obsolete. If you encounter a similar problem, please post a new question." – Adam Lear
If this question can be reworded to fit the rules in the help center, please edit the question.

Can't reproduce on CHrome. The current behavior is that spaces are just removed, which makes sense since they delimit tag endings. Probably got fixed in the span of 3 years – Manishearth Jul 3 '13 at 8:34

I think I see what you mean.

I'm unclear why "typing a space" is necessary, though -- simply do this:

  1. go to http://meta.stackexchange.com/questions/ask
  2. [tab] to the tags field
  3. type the beginning of a tag, say "disc", and press [enter]
  4. goto 3.

I thought the extra space was necessary to get the dropdown list. An automatism (ctrl-space gives suggestions in VS and other IDE's). Indeed, if you are careful, the error doesn't pop. But there shouldn't be a need for the error either ;-). Btw, if you do as you say and hit Enter without using the arrow keys first, you submit the question immediately (Op, FF). – Abel Apr 15 '10 at 9:23
perhaps this can be summarized that having two spaces will break the tab==select. It sounds as rather trivial to solve (but doesn't it often). PS: should, on Meta, answers be accepted when a bug is confirmed (as is the case here) to place it on the "TODO" list, however trivial the issue is? – Abel Jul 28 '10 at 13:07
