Troubleshooting Case Number Field No Longer Read-Only

Symptom

After removing the case number field from the Cases module editview, the field is not read-only if it is added back to the layout.

Solution

To make the case number field read-only,

1. Edit 'custom/modules/Cases/metadata/editviewdefs.php'
2. Change the following line:

   array(
   'name'=>'case_number', 
   'displayParams'=>array('required'=>true)
   )
   

   to:

   array(
   'name'=>'case_number', 
   'type'=>'readonly', 
   'displayParams'=>array('required'=>true)
   )
   

3. Save the file
4. Navigate to Admin > Repair > Quick Repair and Rebuild
5. Uncheck Repair Database
6. Click Repair

The case number field should now be read only on the Cases editview.
