Hi Bill, How do you leverage the x:saveState(or preserveModel) functionality?
I have an application that just adds record to a DB and keeps a table (x:datatable) updated with those db records. Should I preserve the state of the x:datatable(maintaining it every time a record is added) or should I be reading the db every time I add a record and repopulating the x:datatable? What is best? Hope my question makes sense. TIA.
