Hi,
When I carry out the sequence of following operation with the version of Castor
0.9.4.1 I do not have a problem !
db.begin();
thequery = createSelect(db...);
result = thequery.execute();
while (results.hasMore()) { ... }
thequery.close();
db.rollback();
db.close();
But when this sequence of operation is carried out with version 0.9.4.3 I have a
crash. The values returned by Query are correct. It is at the time of the rollback()
that the crash occurs.
I did not change anything in the code between the two versions. This one was simply
Re-compiled
The Crash message :
