i have a radiobutton column and name column in my table.
if i select this radiobutton i have to display the name on the screen.
i mapped the radiobutton selectedkey to one attribute which is of type boolean.
and i created one action and assigned it to radio button's onaction.
but if i click on the radiobutton ,it is giving java.lang.nullpointer exception.
could you please tell the solution for this.
thanks in advance.
