Re: JavaScript Errors in the Query Tool Leads to a False Message

Is there a way to reproduce this? i.e force a js error during query
execution? One reason I can think of is using $.ajax({ async: false }) so
the ajax request gets handled on the main thread and anything that throws
on to the main thread gets caught.
