Lachlan,
Thanks very much. I've fixed the code as you suggested.
I'm afraid we have several other uses of
qualifierWithQualifierFormat() that I'll probably have to fix as
well, but fortunately with the Wonder ERXQ class it's nearly as
simple and readable as using the format string. The advantage of
compile safety is probably worth the effort anyway.
Certainly makes it simpler to find problems. Sometimes you can
overlook simple spelling mistakes in strings.
I know it's a moot question, but I'm curious--any ideas as to what
might have caused the failure to recognize 'caseInsensitiveLike' as
an operator?
I really wouldn't know without testing it. I suspect that it's either
confused by the locale with the bare string you've supplied or what's
in your email doesn't match the previously wrong implementation ;-)
Do you think something about their using a Turkish locale could
cause this?
That's quite possible.

Try using EOKeyValueQualifier (which gives you compile safety)
rather than qualifierWithQualifierFormat.
Also try not exposing foreign keys unless you really need to.
public User getUserForLoginId( String loginId, int loginType,
Preference aPreference ) {
NSMutableArray andQuals = new NSMutableArray();
andQuals
.addObject( EOQualifier.qualifierWithQualifierFormat( "(deleted =
0) or (deleted = nil)", null ) );
if( aPreference != null )
andQuals
.addObject( EOQualifier.qualifierWithQualifierFormat( "accountId =
" + aPreference.account().id(), null ) );
if( loginType == USERNAME_LOGIN )
andQuals
.addObject( EOQualifier.qualifierWithQualifierFormat( "username
caseInsensitiveLike %@", new NSArray( loginId ) ) );
andQuals.addObject( new EOOrQualifier( new NSArray( new
Object[] {
new EOKeyValueQualifier( User.DELETED_KEY,
EOQualifier.QualifierOperatorEqual, 0 ),
new EOKeyValueQualifier( User.DELETED_KEY,
EOQualifier.QualifierOperatorEqual, NullValue )
} ) );
if ( aPreference != null )
andQuals.addObject( new EOKeyValueQualifier( User.ACCOUNT_KEY,
EOQualifier.QualifierOperatorEquals, aPreference.account() ) );
if ( loginType == USERNAME_LOGIN )
andQuals.addObject( new EOKeyValueQualifier( User.USERNAME_KEY,
EOQualifier.QualifierOperatorCaseInsensitiveLike, loginId ) );
EOQualifier qual = new EOAndQualifier( andQuals );
EOFetchSpecification fetchSpec = new
EOFetchSpecification( "User", qual, null );
fetchSpec.setRefreshesRefetchedObjects( true );
NSArray matchingUsers =
ec.objectsWithFetchSpecification( fetchSpec );
