To test, apply the patch and go to Administration -> MARC modification templates. - If necessary, add a template with at least one action. - Check the browser console, there should be no errors. - Click the "Edit" button corresponding to one of the template actions. - The details of the action should load correctly in the edit form and there should be no errors in the console. -- You are receiving this mail because: You are watching all bug changes.
