i learned a lot there, but i don't know if this is a bug.
($.data(body[0],'events')||$._data(body[0],'events')) turns out to be an object instead of array,
by the way, the second one $._data(body[0],'events') is undefined.
i'm new to this, wish some help
thanks stworthy

Hi
my datagrid's detail view setting is

Code:

view: detailview,
detailFormatter:function(index,row){
    return '<div class="ddv" style="padding:5px 0;overflow:auto;padding-right:10px"></div>';
},

the error ocurrs in datagrid-detailview.js here at the last line

Code:

bindEvents: function(target){
var state = $.data(target, 'datagrid');

if (state.ss.bindDetailEvents){return;}
state.ss.bindDetailEvents = true;

var dc = state.dc;
var opts = state.options;
var body = dc.body1.add(dc.body2);
var clickHandler = ($.data(body[0],'events')||[b]$._data(body[0],'events')).click[0][/b].handler;

and it says "Uncaught TypeError: Cannot read property 'handler' of undefined "
please help out
and
($.data(body[0],'events')||$._data(body[0],'events')) looks like

Code:

Object {mouseover: Object, mouseout: Object, click: Object, dblclick: Object, contextmenu: Object}
click: Object
    224: function (e)
    {__proto__: Object
contextmenu: Object
dblclick: Object
mouseout: Object
mouseover: Object
__proto__: Object
