People field - unable to disable

@Marcin,

I'm sorry, I couldn't reproduce the issue on my form. The function woks just fine.

Try to debug your code, maybe there is a typo in the field internal name or something else.

Or simply use the this code:

fd.field('ApprovedBy').value = props[i].Value;
fd.field('ApprovedBy').ready().then(function (field) {
  if (field.value) {
     field.disabled = true;
}
