Clearing lookup value using REST updateRecord() RRS feed

  • Question

  • Hi, I am writing custom javascript code to clear a lookup field, and then continuously check to see if the field has been populated.  A workflow is triggered to run once the lookup field has been changed and is set to place a new lookup value into the field.  Once the workflow populates the lookup field, the javascript code stops checking the field and opens the new record.

    Currently, I am using a REST SDK updateRecord call to clear the field, but it does not seem to be working from my check field function.  I can use a Xrm.Page.getAttribute().setValue() call to clear it, but then I need to save the record so the workflow can read it. 


    After saving the page, the timeout() function call does not run.  So I am wondering if there is a way that I can use either the Xrm calls or the REST updateRecord to clear the field for my custom workflow to trigger

    function onClick() {
            var updatedQuoteHeader = {};
            updatedQuoteHeader.ber_RecentQuoteId = { Id: null, Name: null, LogicalName: null };
            SDK.REST.updateRecord(quoteHeaderId, updatedQuoteHeader, "ber_quoteheader",
                function (e) {
                    alert("REST call failed");
    var myEmailGuid = null;
    function check_ber_recentquoteid() { 
        SDK.REST.retrieveMultipleRecords("ber_quoteheader", "$select=ber_RecentQuoteId&$filter=ber_quoteheaderId eq (guid'" + quoteHeaderId + "')&$top=1",
            function (quoteheader) {
                //alert("quoteheader[0].ber_RecentQuoteId: " + quoteheader[0].ber_RecentQuoteId);
                if (quoteheader[0].ber_RecentQuoteId.Id != null) {   //if it has a value, then assign myEmailGuid the GUID
                    //alert("assigned new email");
                    myEmailGuid = quoteheader[0].ber_RecentQuoteId.Id;
                    Xrm.Utility.openEntityForm("email", myEmailGuid);
            function (e) {
            function () {
    var myInterval;
    function timeout() {
        myInterval = setInterval(function () {check_ber_recentquoteid();}, 5000);

    Thanks for reading,
