Weird... putting it in it's own class file works just fine. Turns out it was not my qualifier, but something to do with the way I am using an ERXDisplayGroup.

I have this code in my search method:

displayGroup().setQualifier(qual);
displayGroup().fetch();

public ERXDisplayGroup<Person> displayGroup() {
if (displayGroup == null) {
EODatabaseDataSource dataSource = new EODatabaseDataSource(

session().defaultEditingContext(),
Person.ENTITY_NAME);

displayGroup = new ERXDisplayGroup<Person>();
displayGroup.setDataSource(dataSource);

displayGroup.setNumberOfObjectsPerBatch(10);
displayGroup.setSortOrderings(Person.LAST_NAME.ascInsensitives());
}
return displayGroup;
}

If I change the code in the search method to:
displayGroup().setObjectArray(Person.fetchPersons(ec, qual, null));

everything works as fast as I would expect. Anyone have insights into why the way I was trying to use ERXDisplayGroup was so slow?

Thanks,

Joe

Uhhh, bizarre

IllegalArgumentException: <NSSelector> method is not public: public com.webobjects.foundation.NSArray

:D Looks public to me.

Try making the delegate an actual class in its own java file then.

Hi Ramsey,

Adding that code I get the following stack. Did I miss anything?
