Having spinners in each p:columnS of my dataTable i saw that the valueChangeListener methode is simply never called....so i tried the f:ajax listener, which is called but can't provide me with the selected value....it's madness!! I also read this great page : When to use valueChangeListener or f:ajax listener? but still i can't get it working..
I guess that the construction within a p:columnS is a bit more complex, for example : it's difficult to give a dynamic ID to each selectOneMenu (even with rowIndex from dataTable and colIndex from p:columns component) SO has someone ever resolved that ???
