Javascript on Case form - Set null value on subject field

Posted on by CU13011037-0

Hello,

When I use a javascript to set null value on subject field on case form, the "id" value of field is set correctly to null, but the text in field remain populated and not return to blank value.

So for the user, seems that the subject is setting, even if the subject is null, and effectively, when the user try to save the record, the system rise an error for mandatory field subject.

There is a way to reset to empty string the field "subject" when I use formContext.getAttribute("subjectid").setValue(null) to null?

In the attachment, the value of my "subject" field after formContext.getAttribute("subjectid").setValue(null) instruction.

Thanks in advance

Hi,
The lookup value of the Subject field (its ID, entity type, and name) is cleared correctly, but the control UI is not refreshed immediately. As a result, the old subject text still appears on the form even though the underlying value is null. This creates confusion for the user, since the field looks populated until they try to save, at which point Dynamics throws an error because Subject is a mandatory field.

To resolve this, you need to clear both the attribute value and the control display value. You can do this with:
formContext.getAttribute("subjectid").setValue(null);
formContext.getControl("subjectid").setValue(null);

This ensures the Subject field is fully cleared—both the backend value and what the user sees on the form.

Hope this helps.

Thanks!
