I have some GUID fields in a custom list. I've created a webpart to manage that list. By code I can edit the content of these fields successfully (with JSOM).
However, I can't add the values for these fields when I edit the list item using the SharePoint UI (EditForm.aspx). These fields don't show any control like a textbox or dropdownlist for example. Is there any way to do it?
Thanks in advance
