Given the following code:

loTest=CREATEOBJECT('Test')
MESSAGEBOX('Data session after having created Test: '+STR(SET('DATASESSION')))

loPrivateData=CREATEOBJECT('PrivateData')
SET DATASESSION TO loPrivateData.DataSessionID
MESSAGEBOX('Data session now switched to 2: '+STR(SET('DATASESSION')))

loTest.Go()

DEFINE CLASS Test AS Custom
FUNCTION GO
MESSAGEBOX('Data session inside method is switched back to 1: '+STR(SET('DATASESSION')))
ENDFUNC
ENDDEFINE

DEFINE CLASS PrivateData AS Session
ENDDEFINE

Can someone explain me why calling a method from the Test object resets the data session to 1? We are sitting on data session 2 when calling that method. Why it is resetting itself to 1?

I need to maintain the data session state. How can I make that work?
