[Opensource] deleteAll() error?

[Gabor Nagypal]

Hi,

I use Expresso5.3rc3. Trying to run deleteAll() in a transaction yields 
the following error message:
ERROR [main] dbobj.DBObject (DBObject.java:1818) - Error performing 
deleteAll
com.jcorporate.expresso.core.db.DBException: 
com.jcorporate.expresso.core.db.DBConnection.next():Error retrieving 
next row for statement DELETE FROM Resource WHERE id = 
'expressoTest:#i-1064404574995-16294950' 
(org.vicodi.expresso.dbobj.LinkResourceResRoleDBO):Connection is closed. 
  Operation is not permitted.

"In transaction" means using the
myPool = 
DBConnectionPool.getInstance(TestSystemInitializer.getTestContext());
myConnection = myPool.getConnection();
myConnection.setAutoCommit(false);
xxxDBO resource = new xxxDBO(myConnection);
pattern.

As all of the other operations work such way (including simple delete()) 
I suppose it is an error in Expresso.

Regards,

Gabor
