Status: Unverified
FACT(s) (Environment):
OpenEdge 10.1B
All Supported Operating Systems
SYMPTOM(s):
.Net application passes Dataset to AppServer as an INPUT-OUTPUT DATASET-HANDLE parameter
ABL code on the AppServer modifies the Dataset and adds one or more tables to it
.Net generates a runtime exception because the returning Datasets schema does not exactly match that which was passed to the AppServer
Index was outside the bounds of the array.
CAUSE:
When passing a Dataset as an INPUT-OUTPUT parameter the schema must be the same for both sides. We use the schema passed in from the client as the schema for the returning DataSet.
FIX:
If the Dataset must be modified (i.e. tables or fields added) on the AppServer side then pass two parameters, one as INPUT and the other as OUTPUT.
