Should be judged before use.

If you use iframe in tabs the "conent", the script from the network, may be slow to load.
Prevent users from early action (for example:modal), or to improve the script loading speed.

You can try to provide some code or a reference patch.

I tried really have this problem, but I do not know if this will affect the program.
I'm using version 1.4.1, but the patch fixes this problem.

I'm sorry, I made a mistake.
The new patch does not support object,it appears in my second datagrid.

demo:
formatter: function(value,row,index){
    if (row.user){
        return row.user.name; //In the new patch, the user is a string.
    }
}

error:Uncaught TypeError: Cannot read property 'name' of undefined.

Perhaps this is not a bug.

Turned out to be more than a formatter.

1.4.1.patch - 02/28/2015

While loading two datagrid, the second can not read data.

demo:

$(function(){
  $("#t1").datagrid({...});
  $("#t2").datagrid({...});
});

<table id="t1" />
<table id="t2" />

This patch will cause this problem, prior to the patch is normal.

Thank you!
I find the reasons.
Because demo site set up font.
But my project does not set the font, resulting in "&nbsp;" takes up some width.

Recommendation:
If the font is necessary, can be added to the package.

see the picture

this problem does exist

[page] parameter, second post is 0

after using the patch, [page] parameter is 1

however, rows.length == 0, it will still be post twice

That is async

many controls extended from validatebox.

对不起，我英文比较差，希望可以用中文表达。

我是一个 EasyUI 爱好者，今天怀着期待的心情试用 1.4 版本，总体感觉都很好。

也发现了一些问题，当然也还有尚未发现的。

在此提出希望可以起到一些作用。

主要是针对继承于 Panel 的一些控件使用上出现了一些问题。

Tabs 使用 content 装载 html or js 的时候 js 会执行2次。

dialog 使用 content 装载 html 时 无法设置 buttons。

使用 href 装载 html 时 不再像以前一样自动调整高度（这个也许是正常的）。

以下内容为 google 翻译。

I'm sorry, my English is poor, hope you can use Chinese expression.

I was a EasyUI enthusiasts, today expectant mood trial version 1.4, the overall feeling is very good.

Also found some problems, of course, there are still undiscovered.

In this raised some hope that we can play a role.

Mainly for inherited some problems in the Panel's some controls use.

Tabs use of content when loading html or js js will perform two times.

dialog using buttons can not be set when content loading html.

No longer automatically adjust the height as before loading when using href html (this may be normal).
