I just try to migrate Ajax4jsf code google-house into Seam and richfaces. And modify code EmployeeTable.java and Employee.java. Orignal jsf page call employee like: #{employeeTable.employee.address} So when switching between tabPanel, pages can keep all typing information. But after I change them into seam EmployeeTable code like: @In @out Employee employee; and pages: #{employee.address} So how to activate employee session to keep its information?
