This is a simple list of Users in a table with Hide Footer turned on. The model has a UI-only checkbox field, and there is a pair of row actions that toggle the field on and off.
When you first click the Toggle On action, nothing happens. Check the browser (Chrome) console (Ctrl+Shift+i) and you will see the javascript error “Uncaught TypeError: Cannot read property ‘find’ of undefined”
To prevent the error, unselect the Hide Footer option on the table.
Could I please have the last two days back?
