Controller functions being called twice, passed "css" second time?

[eluser]Unknown[/eluser]
While debugging my application I am noticing that my controller functions are getting called twice on page load.

The argument being passed the second time to my function is always the string "css". Because of this I am not getting any data back because the second function call is overwriting my $id parameter and ruining my query.

Anyone have any explanation or ideas about this?
