hi All:

>From the GWT doc it says:

one of 4 special methods are required on all entities as they are used by 
the RequestFactory servlet is:

Integer getVersion()


but i am working on a system that already has a DB schema(MySql), i'd like 
to use RF to do CRUD operations, so do i have to insert each table a version 
column? is there other way i can use RF without had each table a "version" 
column?

thanks very much.
