Please run the demo and double click the son column. When the cell is edit state, it show [Object Object]. It is not what I want. When exit edit it resume correctly in IE but wrrong in chrome.
Orginally I didn't want to edit value in cell, so you can see I have set the readOnly:true attribute. It can't select the text in grid with extjs4. I just want to use CellEditing plugin to be able to select the text in grid.
