var copylineItems = $filter('filter')($scope.panelsObj, {
isSelected: true
});
var primaryLineNo = [];
for (var i = 0; i < copylineItems.length; i++) {
primaryLineNo.push(copylineItems[i].primaryLineNo);
}
if (primaryLineNo.length > 0) {
cfpLoadingBar.start();
APTS_PanelConfigController.cloneLineItems(cartId, primaryLineNo, function(result, event) {
if (event.status) {
if (result) {
$scope.panelsObj.splice(0, $scope.panelsObj.length);
