Based on this thread and an earlier one on the same topic, I think I'm
going to rework my index list pages something like this.
The link to the delete function will include the record id, index row
number of the record and number of rows on the page.
When the user clicks the delete button, the jquery will lock out the
navigation links and send an ajax callback to the controller.
The ajax call back will delete the record, then fetch the succeeding
records to fill the page. The returned javascript will rewrite the index
list from the deleted row to the end, update any page count or row count
indicators and unlock navigation.
It seems to me like that's the best combination of agile user experience
and accurately representing the state of the database.
The only thing left out is notifications/refreshes if another user deletes
one of the records on the page. I suppose the way to do that is for the
browser to periodically ping the server ...
