I have a case on which my data will be displayed on a DataTable, the source is Database and the data is being fetched within my back bean constructor.
My Question is how helpful richfaces can be ensuring the consistency in case the data on the database has been changed (the "to be selected later on" row has been deleted for example) since last request, and the user already select a row on the datatable and that row to be marked as selected on my model.
UI components not intended to care about model changes, them just get model values you providing. So it depends on how you organized such synchronization by implementing dataModel. check richfaces demo dataTable and extendedDataTable samples with simple models implemented. full sources link there jboss.org/richfaces/demos
