Blog XrmMtl - CRM 2016 – Update lookup field bug

sample.js

//Create the lookup value object
var lookupReference = [];
lookupReference[0] = {};
lookupReference[0].id = “{a0c68c89-9752-e311-93f9-00155d78043f}”;
lookupReference[0].entityType = “new_entityname”;
lookupReference[0].name = “Display name”;

//Magic happens here
lookupReference[0].type = “lookup”;

//Update the lookup field
Xrm.Page.getAttribute(“new_entitynameid”).setValue(lookupReference);
