When using ORDA .new() command to create new entities for a table, the UUID (as primary key) is actually created at different times depending on context. When running in single user mode, the UUID is created once entity.new() is called like so:

// Single-user example $e:=ds.Table_1.new() // $e.UUID is created here $status:=$e.save()

For client-server, the UUID is actually created once entity.save() is called like so:

// Client-server example $e:=ds.Table_1.new() // $e.UUID is null here $status:=$e.save() // $e.UUID is created here

Keep this in mind when trying to use the UUID value in ORDA.
