Ajout programmatiquement d'un dataTable, Chart, panel à un dashboard, primeFaces 4.0 ?

, dois-je créer un bean pour chaque type d'élément ç-à-d, un DataTableBean, un PanelBean, un ChartBean et injecter les trois beans dans le bean principale DashboardBean du dashboard ? Si c'est le cas comment fusionner les Models(DataTableModel, PanelModel, et ChartModel) ?
