HtmlDataTable is defined by a specification that does not include Serializable implementation. For the HtmlDataTable of this backing bean, you may want to use the 'transient' key word. Also, the state of HtmlDataTable, as well as all other UIComponents, is managed automatically by another interface, StateHolder. If the HtmlDataTable instance is in the view tree, it will be stateful without t:saveState.
