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