Hi Brian, I have seen that interface. If I got more than one action method in one action class. Then when ever you execute/call method(action) in that action class, this prepare method will be called and this setting of list will be executed.
But My main question why the list setting to null value. Isn't it a big, can't we fix it. And in my company i fought with everybody to bring struts2 into project. And now i don't have any answer to this, untill any guys help me. Thanks RS Brian Thompson-5 wrote: > > You might look into using the Preparable interface [1].
