// [11:44] <merlinofchaos> If you load the page from scratch, $input for your identifier will be empty.
// [11:44] <merlinofchaos> So what's going on here is that for $_GET forms, there's no form id, no op button or anything, so they always appear to submit.
// [11:45] <merlinofchaos> FAPI doesn't quite get along with that; sometimes it handles the input being empty right and sometimes it doesn't.
// [11:45] <Bdragon> But if I set #default_value to a static string, it doesn't work either
// [11:45] <merlinofchaos> Right, fapi thinks the empty input is actually input, thus it overrides the default value.
// [11:45] <Bdragon> Ahh, hmm...
// [11:46] <Bdragon> So where would I go to clean it up?
// [11:55] <merlinofchaos> Bdragon: See views_handler_filter_string.inc line 174
// [11:55] <merlinofchaos> Bdragon: That's how i address this problem.
