I'm having trouble getting saveChangesErrorHandler to be called when (for example) the I send a bad HTTP PUT request to the server.

         features : [ {
            name : 'Updating',
            editMode: "cell",
            startEditTriggers: "dblclick,F2",
            showDoneCancelButtons : true,

           saveChangesErrorHandler : function (jqXHR, textStatus, errorThrown) {
                alert("An error occurred while saving the changes: " + textStatus);
            },
            saveChangesSuccessHandler : function (data) {
                alert("Changes saved.");
            },

            <etc>

I see an alert from saveChangesSuccessHandler after a successful save, but never from the error handler. Similarly, a breakpoint in the error handler is never hit.

I tried pasting the handlers above to a sample project that Infragistics sent me for an unrelated issue, and got the exact same behavior. So it's presumably something silly like a typo, but I compared the lines to the docs and I'm not seeing the problem.

Thanks!
