I am getting this notice for each row of my update using Active Record batch_update:
<p>Message: Array to string conversion</p>
<p>Line Number: 1407</p>
The update works fine. Just the error messages get in the way in DEV.
set_update_batch() is the method at 1407.
I am setting error_reporting(0) just before running this batch update request so I can complete my ajax request in DEV. No big deal but it does look like a bug. I am passing in an array not an object to this method if that helps.
