Updating a newly created instance
After creating an instance, the instance has a state "new instance" until it is read again from the database (Get, Reset). This may cause several functions not working properly (see example below).
// does not work - no data is copied to newly creeated instancesr
target_ph.Add(key_value);
target_ph.CopyData(*source_ph,REPL_direct);
// this works, since Reset disables the 'new instance' state
target_ph.Add(key_value);
target_ph.Reset();
target_ph.CopyData(*source_ph,REPL_direct);
