I'll think about it.... I'd want to update it first and it might be a
little while before I have time for that.

Hi
Is there any good help documentation on the 'OO' world rather than the
BOR world.
Thanks
John

Restrictions in 6.20 are:
* No functional methods (which is sad but you'll live)
* Some small changes in persistent object handling (again sad but
liveable).
1. Always add a CREATEINSTANCE static method to your ABAP OO object.
This method should accept in your object key, do a create object step,
and catch any exceptions (e.g. object does not exist) and return the
object in a returning parameter. You can then call the CREATEINSTANCE
step in a task. Double check your binding - I often find it easier to
bind directly to the returning parameter rather than use the _WI_Object
element.
Note: You are not permitted to call the Constructor method directly in
a task, and likewise leave all the LPOR stuff alone -that's for
internal use by the workflow engine only. In NW04s you don't even get
to choose those methods when you create a task so best not to touch
them at all.
2. Absolutely use ABAP OO Events. You should only use BOR events if you
have an SAP provided BOR object and no way of raising an OO event due
to the way that applications config works.
Change documents let you raise ABAP OO events without any problems at
all... and of course you can always raise ABAP OO events from user
exits, BADIs, custom programs, etc. Regards,

Subject: ABAP OO and Workflow (Events, Get a handle etc)
Hello all,
i am currently implementing Workflows baseing on ABAP OO in a 6.20
System (yes i know there are some restrictions, just dont know much
about these restrictions, as i havent yet found any valuable infos).
I do facing some problems and need some ideas:
1. How do i get a handle of a ABAP OO class (included the IF_WORKFLOW
as well as implementation of the respective Methods (find~by~lpor etc))
in my workflow container at runtime?. I do start the workflow with the
WAPI-FB to start a workflow. So far i have tried to wrapp the
find~by~lpor method in another static method which is called from my
workflow. I do pass a key to the task which implements the wrapper
method. The task passes the key to the method and the method should
return a handle which will then passed back to the workflow. Everthing
on the data-level is fine, meaning the key is a valid key (did run the
class in testmode and called the wrapper method with that key and i do
get a valied handle back) . Unfortuantelly the container element of the
workflow which should hold the returned handle is always empty.
2. Is it recommend to use EVENTS as part of ABAP OO to control
workflows or should i better go with a BOR implementation for that
matter?
thanks :)
regards,
Markus
