"Unable to get property 'setValue' of undefined or null reference"

Posted on by USA80

I have the following script that keeps error out when it trys to set the name field to null. The error I get is "Unable to get property 'setValue' of undefined or null reference" I have made sure that the field is spelled correctly and exists on the form. When stepping through the logic in debugger, it does pick up the text field of Name just fine. Issue is when I try to set it to null that it doesn't like it. Please help, thank you.

function onSaveSetName ()
{
var name = Xrm.Page.getAttribute("nhs_description").getValue();
var measurement = Xrm.Page.getAttribute("nhs_measurement").getText();
var separator = ' - ';
    var contractliinetitle = Xrm.Page.getAttribute("nhs_contractdetailtype").getValue();
var contractdetailtype = Xrm.Page.getAttribute("nhs_resultscontractdetailtype").getSelectedOption().text;
var month = Xrm.Page.getAttribute("nhs_resultseffectivemonth").getSelectedOption().text;
var quarter = Xrm.Page.getAttribute("nhs_resulteffectivequarter").getSelectedOption().text;
var year = Xrm.Page.getAttribute("nhs_resulteffectiveyear").getSelectedOption().text;

    var dateFieldValue = new Date(enddate);
    var year = dateFieldValue.getFullYear() + "";
    var month = (dateFieldValue.getMonth() + 1) + "";
    var day = dateFieldValue.getDate() + "";
    var enddate = month + "/" + day + "/" + year;

/*Contract Detail Type: Guarantee = 127130000
   Measurement: Monthly = 127130000, Quarterly = 100000000, Annually = 100000001, By Audit Request Only = 100000002*/


if (contractdetailtype == "Guarantee" && measurement == "Monthly" && contractliinetitle !=null)
{
  Xrm.Page.getAttribute("name").setValue(null);
  Xrm.Page.getAttribute("name").setValue(contractliinetitle + separator + month + separator + quarter + year);
                Xrm.Page.ui.controls.get("name").setDisabled (true);
}

else if (measurement != "Guarantee")
{
Xrm.Page.ui.controls.get("nhs_description").setDisabled (false);
}

}

Seems you are missing publisher name in the name field. What is your entity publisher? try to add prefix with name field like below. Hope this helps.

Hi,

There are no field name without publisher in Dynamics CRM for custom entity, so you should add publisher name before "name". Replace with below lines .

Xrm.Page.getAttribute("nhs_name").setValue(null); Xrm.Page.getAttribute("nhs_name").setValue(contractliinetitle + separator + month + separator + quarter + year); Xrm.Page.ui.controls.get("nhs_name").setDisabled (true);

Hope this helps.

So it should be like this?

Xrm.Page.getAttribute("nhs_description").setValue(null);

Xrm.Page.getAttribute("nhs_description").setValue(contractliinetitle + separator + month + separator + quarter + year);

Xrm.Page.ui.controls.get("nhs_description").setDisabled (true);

Add a alert to check whether you can find field using below script.

alert( Xrm.Page.getAttribute("name"));

If you see null as alert that means field does not exist in the form. You can not set value to the field that does not exists in the form.

An attribute/field needs to be present on a form to be reachable by Xrm.Page.getAttribute(attributeName).

However, it can be hidden, or placed in a hidden section or tab.

If found useful, please mark the answer as verified.

few things :

1. make sure your name and description field and others are on the form

2. if its a custom field as highlighted by Goutam - it has to be like nhs_name

3. try using Xrm.Page.data.entity.attributes.get("nhs_name or name").setValue(null);

4. or simply say Xrm.Page.getAttribute("nhs_name or name").setValue(" ");

As highlighted below:

function onSaveSetName ()
{
var name = Xrm.Page.getAttribute("nhs_description").getValue();
var measurement = Xrm.Page.getAttribute("nhs_measurement").getText();
var separator = ' - ';
var contractliinetitle = Xrm.Page.getAttribute("nhs_contractdetailtype").getValue();
var contractdetailtype = Xrm.Page.getAttribute("nhs_resultscontractdetailtype").getSelectedOption().text;
var month = Xrm.Page.getAttribute("nhs_resultseffectivemonth").getSelectedOption().text;
var quarter = Xrm.Page.getAttribute("nhs_resulteffectivequarter").getSelectedOption().text;
var year = Xrm.Page.getAttribute("nhs_resulteffectiveyear").getSelectedOption().text;

var dateFieldValue = new Date(enddate);
var year = dateFieldValue.getFullYear() + "";
var month = (dateFieldValue.getMonth() + 1) + "";
var day = dateFieldValue.getDate() + "";
var enddate = month + "/" + day + "/" + year;

/*Contract Detail Type: Guarantee = 127130000
Measurement: Monthly = 127130000, Quarterly = 100000000, Annually = 100000001, By Audit Request Only = 100000002*/

if (contractdetailtype == "Guarantee" && measurement == "Monthly" && contractliinetitle !=null)
{

alert(Xrm.Page.getAttribute("name"));

Xrm.Page.getAttribute("name").setValue(null);
Xrm.Page.getAttribute("name").setValue(contractliinetitle + separator + month + separator + quarter + year);
Xrm.Page.ui.controls.get("name").setDisabled (true);
}

else if (measurement != "Guarantee")
{
Xrm.Page.ui.controls.get("nhs_description").setDisabled (false);
}

}

One more point guys,

in place of using alert method you can use

console.log('Your Expected text / variable name').

this will not pop up alert message rather the log will get generated within f12 debugger toll.

check by using this wherever you feel the error comes in.

I don't get the error anymore ,but having another issue:

My contractlinetitle variable is a text field but when I do the debugger the result that it shows is "[[object Object]]" and not the actually what is in the field currently.

Any ideas as to why?

Hi,

What is the field type of nhs_contractdetailtype attribute? Seems this is lookup that's why.

You can retrieve like below.

var contractdetailtype = Xrm.Page.getAttribute('nhs_contractdetailtype').getValue()[0].name;

(you can also use "id": Xrm.Page.getAttribute('<FIELD_NAME>').getValue()[0].id;)
