Status: Unverified
FACT(s) (Environment):
OpenEdge 10.x
SYMPTOM(s):
Passing handle variable as DATASET-HANDLE parameter.
Handle has been reused (it referenced an object that has since been deleted)
Invalid DATASET-HANDLE parameter given. (12314)
CAUSE:
For performance reasons, when deleting an object any handles referencing it are not cleaned up automatically - they merely become invalid.
When the handle is passed as DATASET-HANDLE, a check is made to see if it actually points to a ProDataSet object. As it is pointing to nothing, this check will fail.
FIX:
Clean up the handle by assigning the unknown value to the handle before passing it to the called procedure.
