Workflow and ABAP OO

Question

Hi,
I have read the excellent blogs on Workflow and ABAP OO by Joycelyn Dart (/people/jocelyn.dart/blog/2007/07/16/referencing-bor-objects-in-abap-oo-classes). I have sucessfully created a  BO (of type SIBFLPORB) in my class. However, I cannot figure out how to retrieve the workitem container that holds the BO. I have used macros before in workflow programming exists, but there I get the container from a workitem context. I can't find the workitem context in my class. Please provide me with some code samples of how I can retrieve the workitem container that holds the BO.
I am considering passing the workitem id to the method and reading the container via SAP_WAPI_READ_CONTAINER. If this is a good solution, then I see no point in having the BO as an attribute of the classe. Is it a good solution?
Thanks!

I am probably missing something obvious here (or we are not even speaking about a same thing), but I still try to clarify my point.
>I could of course just pass the necessary data as parameters to the class
This is the part that I don't really understand. If you already have an instance of a class existing (=there is an object instantiated), which has the BO as an attribute, there shouldn't be any need to change a signature of any method(?). The only thing you need to enhance is the constructor of your class.
Currently you create the BO instance as an attribute in your constructor method (isn't this correct?). Just create the attributes you need from the BO into your class, and "populate" them in your constructor. Or if it is an method that you need, just create a similar method (=you can copy the code) into your class.
This all might be much easier than using the WF macros, which shouldn't be that difficult either - as Jocelyn says:
"You will still need to use BOR macros in your ABAP OO classes if and only if you want to call BOR attributes and methods in your ABAP OO methods.
If you need to do this then make sure you include the BOR macro definitions in your class by putting the special include program <cntn02> in the "Macros" section of your ABAP OO class."
