title: PrimeFaces DataTable CellEdit get entity/object
body: <p>I have a datatable which displays various entities based on a List&lt;>. When I select a cell for editing I want to be able to also get the entity somehow in order to update it.
  Of course there is event.getRowIndex, which I can then use with the List&lt;>, but that is not always convenient. Is there perhaps another way to get the entity from CellEditEvent?</p>
