When using composite keys, you need to consider few points:

In your SELECT statement (select_command), you may try to select a first column as special concat value that is based on composite keys. This will handle the listings as first column data must be unique.

For insert/update/delete, you will need to use custom events on_update/on_insert/on_delete to parse the posted id and perform desired operation. Refer demos/editing/custom-events.php for help.
