I'm trying to set lookup field value using javascript. My script gives me "An error has occurred. Please return to the home page and try again", but everything works well. This is my code:
var lookupVal = new Array();
lookupVal[0] = new Object();
lookupVal[0].id = lookup.savedEntityReference.id;
lookupVal[0].name = lookup.savedEntityReference.name;
lookupVal[0].entityType = "new_agreement";
var existingValue = Xrm.Page.getAttribute("new_agreement").getValue();
if (existingValue === null) {
Xrm.Page.getAttribute("new_agreement").setValue(lookupVal); //error is in this row
}
