public String button2_action() {
        // TODO: Process the button click action. Return value is a navigation
        // case name where null will return to the same page.
        System.out.println("Invoke");
        return null;
    }i don't know what is problem there if found any solution, help me.

You need to make sure that the getter of the datatable value returns exactly the same list in the apply request values phase of the form submit as it did during the render response phase of the initial display. Only this way JSF can find out which action which row was been invoked. Alternatively you can also place the data bean in session scope (which may have more impact), or use for example Tomahawk's t:dataTable with preserveDataModel attribute set to "true".
