your first line shows
final TextField tx = new TextField("cell", new
PropertyModel(values[row][col],"data"));
But I got java.lang.IllegalArgumentException: Parameter modelObject cannot
be null
I have put
final TextField tx = new TextField("cell", model);
but this time I did not get any exception
BUt validate is not working. so i am not able validate. please explain. I am
using your code only.
Please check
