Hi,
how can i set the same source to two trees but not load the datas twice?

var records = sk.tree.getTopologyTree(“/Topology/GetTopologyTree”);

// TOP TREE
$(‘#topTree’).jqxTree({ source: records, allowDrag: false, allowDrop: false, width: 300, height: 400 });

// TREE FOR COMBOBOX IN POPUP
$(‘#ParentNodesTree’).jqxTree({ source: records, allowDrag: false, allowDrop: false, width: 200, height: 220 });

the #ParentNodesTree is for a jqxDropDownButton…..
