Buttons not working - swf found

Hi all,

I'm trying to use TableTools on my table - I don't get any 404s, so the SWF is found, but the only button that works is the print one. My HTML imports are as follows:

<link rel="stylesheet" type="text/css"
	href="<spring:url value="/resources/css/jquery.dataTables.css"/>" />
<link rel="stylesheet" type="text/css"
	href="<spring:url value="/resources/css/jquery.dataTables.yadcf.css"/>" />
<link rel="stylesheet" type="text/css"
	href="<spring:url value="/resources/css/TableTools.css"/>" />
<script type="text/javascript"
	src="<spring:url value="/resources/js/jquery/jquery-1.8.2.js" htmlEscape="true" />"></script>
<script type="text/javascript"
	src="<spring:url value="/resources/js/jquery/jquery.dataTables.min.js" htmlEscape="true" />"></script>
<script type="text/javascript"
	src="<spring:url value="/resources/js/ZeroClipboard.js" htmlEscape="true" />"></script>
<script type="text/javascript"
	src="<spring:url value="/resources/js/TableTools.min.js" htmlEscape="true" />"></script>
<script type="text/javascript"
	src="<spring:url value="/resources/js/helperTable.js" htmlEscape="true" />"></script>

while my JS code is as follows:

					var oTable = jQuery('#helperTable').dataTable({
						"sDom": 'T<"clearfix">lfrtip',
						"aLengthMenu" : [ [ 10, 25, 50 ], [ 10, 25, 50 ] ],
						"bPaginate" : true,
						"bFilter" : true,
						"bSort" : true,
						"bLengthChange" : true,
						"bInfo" : true,
						"bAutoWidth" : false,
						"sPaginationType" : "full_numbers",
						"aaSorting" : [ [ 5, "desc" ] ],
						"aoColumnDefs" : [ {
							"sType" : "date",
							"aTargets" : [ 5 ]
						}, {
							"bVisible" : false,
							"aTargets" : [ 6, 7, 8 ]
						} ],
						"oTableTools": {
							"sSwfPath": "/helpers/resources/js/copy_csv_xls.swf"
						}
					});

I'm also using the YADCF plugin to generate column filtering - might this be conflicting?

Thanks in advance
