> When a RichFaces Tab of a TabPanel contains a RichFaces DataTable the model of the DataTable is accessed even if the Tab is not rendered at all.
> Since the retrieval of the data table data might include costly database operations this is a serious performance issue.
> The issue seems to be related to the state saving of JSF: the methods are not called during encodeAll() but during state saving of view.
