Hi Andy,

Hello All,
When org.apache.ojb.broker.accesslayer.sql.SqlQueryStatement.TableAlias is used
for abstract class (has extent classes declared, but not mapped to any table
itself) it may initialized with tableName=null. This situation later produces a
problem, because tableName is being used for TableAlias identity
(equals/hashcode):
I'm virtually certain that this is fixed in CVS. Some time ago a similar
error message was posted
http://mail-archives.apache.org/mod_mbox/db-ojb-user/200408.mbox/[EMAIL

If possible please try latest version from CVS (check out
OJB_1_0_RELEASE branch). Or do you use a CVS version?
regards,
Armin
