SimpleLdapTemplate.search failing - resetting values?

[qualcommLisa]

I haven't changed my code since yesterday but it isn't working today. Suddenly the code that does the mapping from the found context into the person instance gets called 2x: the first time is fine but when it is called again the context is null! I have no idea what is triggering the 2nd call.

	public List<QcPerson> findByFilter(Filter filter) {
		logger.debug("findByFilter called with filter: " + filter.encode());
		List<QcPerson> ldapPersons = new ArrayList<QcPerson>();
		
		try {
			ldapPersons = simpleLdapTemplate.search(
					DistinguishedName.EMPTY_PATH, filter.encode(), new PersonContextMapper());
		} catch (org.springframework.ldap.NameNotFoundException nnfe) {
		logger.debug("No records were found using filter: " + filter.encode());
		} catch (Exception e) {
			logger.debug(StackTraceUtil.getCustomStackTrace(e));
		}
		return ldapPersons;
	}

When I execute the app, the search is able to get the context of the record and then it executes the new PersonContextMapper() as expected. Here is the PersonContextMapper nested class:

	private static final class PersonContextMapper extends
			AbstractParameterizedContextMapper<QcPerson> {
		@Override
		protected QcPerson doMapFromContext(DirContextOperations context) {
			QcPerson p = getQcPerson(context);
			return p;
		}
	}

NOTE: Whether or not I do the full mapping within this method or call the external method that maps each of the fields I have the same problem. Here is the beginning of the static getQcPerson(context) method:

		DirContextOperations context = (DirContextOperations) ctx;
		QcPerson p = new QcPerson();

		DistinguishedName dn = (DistinguishedName) context.getDn();
		String uid = dn.getValue("uid");
		logger.debug("dn from context is [" + dn + "]");
		logger.debug("setting uid to [" + uid + "]");
		if ( uid != null) p.setUid( uid );
                ...

Note the 2 logger.debug lines in the CODE above, and now look at the output below. The 2 lines are repeated because the getQcPerson() method is somehow called 2x. The 2nd call has a null dn so everything fails.

2010-10-01 03:01:50,939 DEBUG com.qualcomm.ldap.model.dao.PersonDaoImpl, 87 - findByFilter called with filter: (employeeNumber=83030)

I've spent hours on this and it worked perfectly fine yesterday. My app is using:
<spring.version>3.0.3.RELEASE</spring.version>
<spring.ldap.version>1.3.0.RELEASE</spring.ldap.version>

Please help asap. External teams are supposed to be using my app in their integration tests today!

The problem was that the testing I did yesterday accidentally created a user with a null uid which is part of the dn. When I queried by the employeeNumber it found both records and kept crashing on the 2nd record.
I knew the code worked yesterday.
