I guess you try to save the instance of a component (HtmlCommandButton)
in your saveState method. Looks like you have a ArrayList whihc contains
those instances.
Try to use UIComponentBase.saveAttachedState and give a list or the
instance of the component as the second parameter. Use
UIComponentBase.restoreAttachedState method the restore the state of the
component(s).
