My attempted use of the Excel-like auto-fill feature fails with:
Uncaught TypeError: Cannot read property 'top' of undefined in Chrome and
TypeError: liner.offset(...) is undefined in FireFox.

I don't know where to go from here and would appreciate any help.

Trace:

• Editor.bubblePosition, tm.js:101443
• (anonymous function), tm.js:101316
• jQuery.event.dispatch, jquery-2.1.4.js:4435
• jQuery.event.add.elemData.handle, jquery-2.1.4.js:4121

The (anonymous function) above reads:

    // Keep the bubble in position on resize
    var namespace = this._formOptions( opts );
    $(window).on( 'resize.'+namespace, function () {
        that.bubblePosition();
    } );

The code where the error takes place is:

    // Correct for overflow from the top of the document by positioning below
    // the field if needed
    if ( liner.offset().top < 0 ) {
        wrapper
            .css( 'top', position.bottom )
            .addClass( 'below' );
    }

liner is defined earlier in the function at this code:

Editor.prototype.bubblePosition = function ()
{
    var
        wrapper = $('div.DTE_Bubble'),
        liner = $('div.DTE_Bubble_Liner'),
        nodes = this.s.bubbleNodes;
...

Ajax load:

{"draw":1,"recordsTotal":3,"recordsFiltered":3,"data":[["WzNd",3,1,"2","ABC"],["WzRd",4,2,"300","ABC"
],["WzVd",5,3,"3001","35"]],"RowNames":["^","Id","DatabaseConnectionId","TableSchema","TableName"]}

Note that after this code executes, both liner and wrapper are objects with length 0.

The error occurs after releasing mouse button on text columns, after clicking a dialog box option (other than cancel) on numeric columns. Note that editing from within the primary editor form works perfectly, including multi-row edits.

The somewhat trimmed DT/Editor init code:

var restUrl = '/MyApp/API/Crud' + '?e=' + '4';
function restAjaxCall(method, url, data, successCallback, errorCallback) {
    $.ajax({
        method: method,
        url: restUrl,
        data: JSON.stringify(data),
        dataType: 'json',
        contentType: "application/json"
    })
    .done(function(json) { successCallback(json); })
    .error(function(xhr, error, thrown) { errorCallback(xhr, error, thrown); });
};

var editor;
$(document).ready(function() {
    var reportTitle = "MyApp Blacklist saved " + moment().format();
    editor = new $.fn.dataTable.Editor({
        idSrc: 0,
        table: "#editor",
        fields: [{"name":"DatabaseConnectionId","data":2,"label":"DatabaseConnectionId"},{"name":"TableSchema","data":3,"label":"TableSchema"},{"name":"TableName","data":4,"label":"TableName"}],
        ajax: {
            create: function(method, url, data, success, error) { restAjaxCall('POST',   url, data, success, error) },
            edit:   function(method, url, data, success, error) { restAjaxCall('PUT',    url, data, success, error) },
            remove: function(method, url, data, success, error) { restAjaxCall('DELETE', url, data, success, error) }
        }
    });

    var $dtOptions = {
        dom: "Bfrtip",
        autoFill: { editor:  editor },
        select: {
            style:'os',
            selector:'td:first-child',
            blurable:true
        },
        serverSide: true,
        deferRender: true,
        processing: true,
        ajax: '/MyApp/API/Crud' + "?e=" + '4',
        columns: [{"data":1,"visible":false,"searchable":false},{"data":2,"searchable":false},{"data":3,"searchable":false},{"data":4,"searchable":false}],
        buttons: [ /* Various button settings */ ]
    };
    var $dataTable = $('#editor').DataTable($.extend(true, $dtOptions, $dtOverrides));
});
