Try changing these:
private static final String
SORT_ENTITY_TYPE_COL="PersonRolePeer.PERSON_REL_ENTITY_TYPE";
private static final String
SORT_ENTITIY_ID_COL="PersonRolePeer.PERSON_REL_ENTITIY_ID";
private static final String
SORT_ENTITY_NAME_COL="PersonRolePeer.PERSON_REL_ENTITY_NAME";
private static final String
SORT_ROLE_DESC="PersonRolePeer.PERSON_REL_REL_DESC";
to this (remove all the ") :
private static final String
SORT_ENTITY_TYPE_COL=PersonRolePeer.PERSON_REL_ENTITY_TYPE;
private static final String
SORT_ENTITIY_ID_COL=PersonRolePeer.PERSON_REL_ENTITIY_ID;
private static final String
SORT_ENTITY_NAME_COL=PersonRolePeer.PERSON_REL_ENTITY_NAME;
private static final String
SORT_ROLE_DESC=PersonRolePeer.PERSON_REL_REL_DESC;
This will guarantee that you are using the generated table.column_name
strings.

Subject:
addAscendingOrderByColumn method not working
03/22/05 03:02 PM
Please respond to
"Apache Torque Users
List"
Using Torque 3.0
Hello,
I have read over the various posts concerning
addDescendingOrderByColumn method not working when building a Criteria
object. If I do not include the addDescendingOrderByColumn or
addAscendingOrderByColumn, the sql works fine(but does not order of
course). When I add it back, a NullPointerException is thrown when
doSelect() is executed.
The column I am sorting on is a String. I noticed when stepping
through in debug mode, right after the
criteria.add(PersonRolePeer.PERSON_REL_PER_ID, getId()); , the
Criteria object inspection correctly prints out a select statement,
but after executing the addAscendingOrderByColumn line, the criteria
select statement seems blank.
Per the past posts:
I checked and the db name is set in the schema.xml. The db adapter is
also correct in the torque.properties file.
As you can see, in the commented out code , I tried a work around of a
custom criteria which I didn't get working yet either. I'd really like
to use the torque method though instead of a custom criteria. Any
ideas?
Thanks,
Kathy Stone
