Why not use a Container to hold the Session class? I have a Combobox inside a Container Class (done thru visual designer). In the INIT of the Container I Instantiate a Session class (from a .PRG) with the following:

THIS.AddObject('ZipData','GetZipCodeTable')  && Session for ZipCode Table

All the Session class does is open a nationwide ZipCode lookup table, similar to this:

Define Class GetZipCodeTable as SESSION

 Proc Init
  USE ZipTable ALIAS ZipStates IN 0 Shared
 EndProc

 Proc Destroy
  Close Data
 EndProc
	
EndDefine

The Combobox uses this table to display the information. I can drop this control on any Form regardless of its DE or of any other tables currently open and it does its job seamlessly. When you Setfocus to this Combobox you see only its Private Session.
