SuiteCRM 7.13.4 - Subpanel filter button causes javascript error

[gp_lnuff]

The following code worked, although I’m sure I’ve tried it before…

unset($layout_defs["ProspectLists"]["subpanel_setup"]['leads']);
$layout_defs["ProspectLists"]["subpanel_setup"]['prospect_list_leads'] = array (
		'order' => 10,
		'sort_by' => 'name',
		'sort_order' => 'asc',
		'module' => 'Leads',
		'subpanel_name' => 'default',
		'get_subpanel_data' => 'leads',
		'title_key' => 'LBL_LEADS_SUBPANEL_TITLE',
		'top_buttons' => array(
			array('widget_class' => 'SubPanelTopButtonQuickCreate'),
			array('widget_class' => 'SubPanelTopSelectButton','mode'=>'MultiSelect'),
            		array('widget_class' => 'SubPanelTopFilterButton'),
		),
);
  $layout_defs["ProspectLists"]["subpanel_setup"]['prospect_list_leads']['searchdefs'] =
array ( 'name' =>
        array (
            'name' => 'name',
            'default' => true,
            'width' => '10%',
        ),
        );
