Look at the Session class. You can just do this.addobject("oSession","mysession") and have mysession class defined as Session, with your properties (like DataSession=2 - private). However, I'm not sure that any code in your container will switch automatically to this.oSession.DataSessionID datasession - any method or event code executes in the datasession in which the object was created.

So you may just turn the things around and define your bizobjects as sessions - but this has two disadvantages. First, Session is not a container, it doesn't have object members. You can get around it by adding object properties, though, but then they don't have an automatic .parent backlink. Second, Session is a strictly non-visual class.

Another funny thing - I've created the following code:

Define Class mycnt As Container

	Procedure Init
		This.AddObject("oSS","mysess")
	Endproc

	Procedure hi
		?"datasession", Set("Datasession")
	Endproc
Enddefine



Define Class mysess As Session
	DataSession= 2
Enddefine

When I instantiate myCnt, it doesn't create a new datasession (tried with "Add Object Oss as Mysess" as well). However, when I instantiate mysess first, it does create it - but stays at the current one. So I figure the way to go would be to
- create a session object
- set datasession to oSession.nDataSession
- instantiate your bizobject.
