Status: Unverified
FACT(s) (Environment):
OpenEdge 10.0A
SYMPTOM(s):
.Net client is calling a program on the AppServer which passes back a dataset
An Unhandled exception of type
Progress.Open4GL.Exceptions.Open4GLException occurred in progress.o4glrt.dll
Additional information: can't format message: "dataType" argument cannot be NULL.
CAUSE:
The exception is caused by the fact that the temp-tables used within the dataset returned from the AppServer contain fields which are DATETIME data types. The .Net Open Client product does not support DATETIME data types in the OpenEdge 10.0A release.
FIX:
Replace the DATETIME data types in the temp-tables with some other data type
