Samuel,
Ok this gets me in the ball park. In my person entity, I created in my Person
entity:
NSArray<Book> pertinentBooks = null;
NSArray<Book> sortedBooks = null;
@Override
public void awakeFromFetch(EOEditingContext editingContext) {
// TODO Auto-generated method stub
super.awakeFromFetch(editingContext);
NSArray<Show> shows =
PersonShow.SHOW.arrayValueInObject(personShows());
@SuppressWarnings("unchecked")
NSArray<Book> showBooks =
ERXArrayUtilities.flatten(Show.BOOKS.arrayValueInObject(shows));
pertinentBooks =
Book.INSTRUMENT_FAMILY.eq(this.instrumentFamily()).filtered(showBooks);
sortedBooks = Book.BOOK_TITLE.ascs().sorted(pertinentBooks);
}
I put some logs and when a Person is edited, I can get the pertinentBooks array
in the person entity. But I have a toMany to BookPerson:
100 : pageConfiguration = 'CreateEmbeddedBookPerson' => displayPropertyKeys =
("book", "isPrimaryPlayer") [com.webobjects.directtoweb.Assignment]
100 : (pageConfiguration = 'CreateEmbeddedBookPerson' and propertyKey = 'book')
=> componentName = "ERD2WEditToOneRelationship"
[com.webobjects.directtoweb.Assignment]
and of course:
100 : (propertyType = 'r' and relationship.destinationEntity.name = 'Book') =>
keyWhenRelationship = "showBook" [com.webobjects.directtoweb.Assignment]
So I need the list of this relationship to be the sortedBooks from Person. Or
maybe send the sortedBooks array as the list element?
