promptText option ignored on initialization

[havok2063]

I'm trying to have my own promptText on tagbox initialization, but it's not working. I can only get it to work after a tag is input, and then removed. Upon tag initialization, the default promptText of "Enter tags.." is used, and my option is ignored. This is what I'm using.

function initTags(name) {
var tagbox = $(name).tags({
tagData:[],
tagSize:'sm',
suggestions:[],
promptText:'Enter a word or phrase and press Return',
caseInsensitive: true
});
}
How can I fix this? I've tried clearing my cache, and session, and reloading everything from scratch. No such luck. Thanks.
