I have an existing interactive grid..
Select emp_id,deptname,dept_no,emp_name from employees;

Here Deptname was first a pop-up lov but now i need to change it to text field. As i change it to text and save i get the following error:

Column->DEPTNAME->Enable User to-> Sort
Component has been changed by another user and this attribute no longer exists. Please reload the page.

I try reloading and saving again but same issue.

Any suggestions?
