If I create the simplest possible table and add a column in the list view to edit records, this works fine in Cook 3.0.10. In Cook 3.1.4, the id of the record to edit is not passed on. The effect of this is that a new record is created instead.

The HMTL produced in the list view seems pretty identical and the ids for each row are there. I haven't had time to run it in the debugger to see where it loses the id number. If I generate the component with version 3.1.4, when I get to the display item function, the variable $_REQUEST [cid] has the value "array" instead of the id number (s) or the record selected.

I noticed the same behaver, the URL does not contain the ID needed, but instead has /Array at the end, If I type the URL manually with the ID in it it works fine.

Same thing for me with my actual project in Frontend.
The Fly that display the Item is empty

Gonna fix that soon

Fixed.
It was due to the recent router feature.
