form saving twice

Hi

I have same issue as previously discussed with form saving twice. And a message

Cause is setting lookups value set OnLoad page. If I disable that, save is working fine

            if (retrieveEventData.results[0].name != null) {
                var setLookup = [];
                setLookup[0] = {};
                setLookup[0].id = retrieveEventData.results[0].fieldId.toUpperCase();
                setLookup[0].name = retrieveEventData.results[0].name;
                setLookup[0].entityType = "entityname";
                Xrm.Page.getAttribute("fieldname").setValue(setLookup);
                Xrm.Page.getAttribute("fieldname").setSubmitMode("always");
            }

And also got this error - there is no save in javascript code:
