if (crmonce != null) {
var lookup=crmonce.getValue();
if ((lookup != null)) {
if (lookup[0].id != null) {
var test = new Array();
test[0]=new Object();
test[0].id=lookup[0].id;
test[0].name=lookup[0].name;
test[0].entityType=lookup[0].entityType;
formContext.getAttribute(“crmonce_lookp5”).setValue(test);
