<p>I am using <a href="http://code.google.com/p/js2-mode/" rel="noreferrer">js2-mode</a> to edit Javascript in Emacs, but I can't seem to get it to stop using tabs instead of spaces for indentation. My other modes work fine, just having issues w/ js2.</p>

Do you have
```
(setq-default indent-tabs-mode nil)
```
in your .emacs? It works fine for me in emacs 23.0.60.1 when I do that. js2-mode uses the standard emacs function indent-to, which respects indent-tabs-mode, to do its indenting.
