JS Error: suggest has no method

[sc0ttkclark]

I’m getting this on all my sites that have upgraded to 2.2.x (tested on 2.2.1 too). It causes JS to fail, which then breaks every other page of the admin area that uses JS.

Uncaught TypeError: Object [object Object] has no method 'suggest'

This relates to this part of the code added to every page of the WP Admin area:

<script type="text/javascript">
			jQuery(document).ready(function() {

				var bbp_topic_id = jQuery( '#bbp_topic_id' );

				bbp_topic_id.suggest( ajaxurl + '?action=bbp_suggest_topic', {
					onSelect: function() {
						var value = this.value;
						bbp_topic_id.val( value.substr( 0, value.indexOf( ' ' ) ) );
					}
				} );
			});
		</script>

I'm running WP 3.4.2 too
