You shouldn't hard-code your key values. It should look more like this:
ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
filter.exclude(MyEntity.MY_ATTRIBUTE);
filter.exclude(MyEntity.MY_OTHER_ATTRIBUTE);
return filter;
If you want to include a to-one relationship, but none of its attributes (just type and id):
ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
filter.include(MyEntity.MY_TO_ONE_RELATIONSHIP_OBJECT);
return filter;
If you want to include a to-one relationship, and a couple attributes:
ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
filter.include(MyEntity.MY_TO_ONE_RELATIONSHIP_OBJECT).include(MyOtherEntity.ATTRIBUTE);
filter.include(MyEntity.MY_TO_ONE_RELATIONSHIP_OBJECT).include(MyOtherEntity.ATTRIBUTE2);
return filter;
