Okay, I had this long thing typed out on my bug and what I was doing to cause it, but then I figured out how to fix it. But it's still a bug.

In Utility.Control.class.php, the InsertItemAt() function looks like this:


function InsertItemAt(&$Collection, $Item, $Position) {
if (array_key_exists($Position, $Collection)) {
$this->InsertItemAt($Collection[$Position], $Position+1);
}
$Collection[$Position] = $Item;
}


line 3 of that should look like this:

$this->InsertItemAt($Collection, $Collection[$Position], $Position+1);


otherwise, it goes all crazy and gives error messages like this:

Warning: Missing argument 3 for insertitemat() in /Users/dknowles/Sites/vanilla/library/Utility.Control.class.php on line 38

if the bug isn't added to the wiki then yes please add it.
