Error in server-side processing causes "Processing" box to hang, no user feedback

jgentil

Hello. I'm using DataTables with the Server-side Processing plugin and an Ajax source. Sometimes, for whatever various reasons, we return an error instead of a DataTables table array which needs to be presented to the end-user. I can't find any documentation on how to hook into the DataTables ajax call to watch for and handle errors. Is there a jQuery event that I can watch for the error, or a callback I can register for handing errors? Right now it just hangs at "Processing" any time the error is returned, with no user feedback at all.

Thank you!

Er, to update: It looks like it also throws a TypeError because aData is undefined.
