Ext JS: with original first Column's Move/Drag, the next first column losing its data

[holdhope]

hello, all,

I am a beginner of ExtJS.
Today I noticed that when i moved the first column of a grid to other position(for example, 3rd, 4th, etc), the next first column loses it data. Strange enough is that the data-losing only happens to the 'first' column, and it means that if i move the other columns (except for the first), there is no column losing its data.
I mean the feature 'enableColumnMove : Boolean
True to enable drag and drop reorder of columns.' is offered by ExtJS, is there anything i can do? Or is there any possiblity for the error?

Thank you for your help in advance!

You prolly want this in the help forums. But just a quick test on the ExtJS 3.2 examples page, I didn't see this same issue.

@holdhope,

Can you post an example of this happening?

the temporary solution: insert a dummy (empty) column into the first position.

@jgarcia, thank you for your moving the post.
@BlueCamel: I have to use the ExtJS version 2.3.0. No other choice.
BTW, it is not allowed for me to post the web page.
