New Post: SPRequireUnique stopped working

Marc,

I have been using SPRequireUnique on one of my lists for about a month and suddenly it stopped working today.  The list just reached 300 items this morning.

The interesting thing is that the initMsg is being displayed in multiple sections of the page, but not in the list item section of the New Form, where it was previously visible.  It is attached to both the OK and Cancel buttons, the site navigation drop down and two lines at the very top and bottom of the page.

I also examined the core.css and this has not been changed in over a month.

The functionality does not respond when a duplicate has been entered.  I have also tried attaching the columnStaticName back to the Title column with and no changes occured.

I have tried switching different SPServices and JQuery versions for resolution.  The versions that were previously working were SPServices 0.6.1 and JQuery 1.5.

$(document).ready(function() {
		$().SPServices.SPRequireUnique({	
			columnStaticName: "MC_x0023_",
			duplicateAction: 1,
			ignoreCase: "false",
			initMsg: "Please enter the MC#",
			initMsgCSSClass: "ms-vb",
			errMsg: "This MC# has already been recorded in the system.",
			errMsgCSSClass: "ms-formvalidation",
			showDupes: "true"
		});
	});
