title: how should i track changes in datatable record using jsf?
body: <p>Suppose i have an editable table ,which means that i could add/update values to a single record. and this table brings about 20 records from Database.</p>
  
  <p>as i said before i could add or update a single record , so i need to send this only changed record to database to be processed/saved not all the 20 records.</p>
  
  <p>so my question is how to keep track of the changed/modified record back to the database to alert the Database to process only this changed  records?</p>
  
  <p>is this can be done using jsf Datatable feature? using (richfaces -myfaces - icefaces - primfaces - etc--) </p>
  
  <p>thanks in advance</p>
