Hey,
I am creating a service request management application. In that I'm creating a form for the user to fill and submit to raise the requests.
Now while submitting the status of the request would be pending and it would be assigned to respective groups of people who would either accept / reject the request.
Next while the status is pending, I'm allowing the user to change the details of the request which he / she had raised, so that mistakes in the request if any could be rectified by the user.
Now I want to create a validation for it. The validation is, if the user clicks on edit and submits the form without changing any contents of the request, I should show an error message saying "Something needs to be changed in order to submit".
Is there any solution to this, as in any way in which I could do this?
