It appears there might be a bug in the Row Number field. I’m using a custom function to return the loop index. It works great in a query loop but no dynamic data seems to be working in the field. When I manually enter a number I can edit and remove a row as expected but when I use a dynamic tag it adds a new row instead. I tried using a form field and a custom field inside the repeater to pass the loop ID but nothing worked. Is there already a loop index tag somewhere that I missed? If not you might consider adding one that works with the row number field.
Here’s my custom function in case I’m doing something wrong:
function my_loop_id() { return intval( Bricks\Query::get_loop_index() ) + 1; }
Thanks very much for reporting this!
