Initialised object reference

[RODRIGUE Johanna]

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

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 ?
