AW: Initialised object reference

[Becker Stephan (extern)]

Johanna,
 
exception 0001 is defined as a method exception (button exception on =
the
object overview), that's why you should use it; it means the workflow =
can
react via modelled behaviour in the workflow template.
 
I've had the same problem, the operator EX only works in a workflow =
when you
actually have a number. Not to worry, you just test whether it's =
initial (in
a condition) before you do the EX check, then you know your answer..
 
Hth,
Stephan

Betreff: Initialised object reference
 
 
Dear workflow experts,
 
I am using the operator 'EX' to confirm existence of an object =
reference
within a workflow and am receiving an error message:
W8 352  "Operator 'EX' can only be applied to an object reference" when =
the
object reference is initial.
 
I have redefined the method ExistenceCheck for the object and raise the
exception Object does not exist (number 0001) when the object reference =
is
initial.
When I test the object through the object builder and the object =
reference
is initial, the message OO 801 Object does not exist is returned for =
the
initial object reference and <NOTHING> appears as the object reference.
I would have expected the 'EX' check against the initial object within =
the
workflow to return a false result, but instead it returns the object
reference error above.
Any feedback on this would be greatly appreciated !
Thanks for your help
Johanna Rodrigue
PS The documentation specifically mentions not to make use of the =
standard
exception "EXIT_OBJECT_NOT_FOUND" within the implementation of the =
method
"ExistenceCheck" and instead to raise the exception 0001. Can anyone =
explain
why this is so ?
