Hi,

I am get the Id of the Lookup Field on the form with JavaScript. This code works with other Lookup fields on different forms, but not with this one. It is odd. The id field is blank which I have never seen before.

    Hi,

    Not sure if this works but give it a try...

    Remove field from the form and then publish your changes. Now again add the same field on the form and publish the changes.

    Hi,

    The issue above is that your field might not be on the form or have a value possibly. A good check to do is first get the field, then check if the field is null or undefined and then attempt the getValue() function after that check. So for example:

    var field = formContext.getAttribute("someField");
    
    if(field !== null || field !== undefined){
        var fieldValue = field.getValue();
        if(fieldValue !== null) {
            //do something with the value
        }
        else {
            //output and error alert or something else
        }
     }   
    //Shorthand check for value could be this as well
    var field = formContext.getAttribute("someField");
    var fieldValue = (field !== null || field !== undefined) ? field.getValue() : null;
    if(fieldValue !== null) {
        //do something with the value
    }
    else {
        //output and error alert or something else
    }

    Hope this helps. Please mark as verified if you have found that this is a solution.
