SYMPTOM(s):
System Error in a .NET event handler when using CLEAR method of proDataSet then deleting query
Red X across UltraGrid control
FACT(s) (Environment):
ABL Stack trace shows last line of code DELETE QUERY
Windows
OpenEdge 10.2A
CAUSE:
Bug# OE00187017
CAUSE:
The problem occurs when deleting a query object which was the TOP-NAV-QUERY of a proDataSet after using the CLEAR method on the dataset. This causes a memory stomp because of improperly referenced memory.
FIX:
To workaround this issue don't use the CLEAR method on the proDataSet, rather use DELETE OBJECT to delete it and then recreate it when needed.
