Hi there,
I am doing a practice of WO application using MacOSX 10.3, Xcode and
WO5.2.
I've faced a problem of EOSortOrdering and can't work out by myself.
From a previous list view page (Fetch by WODisplayGroup) and pass a
record
to a next page. The record (EntityA) has to-many relationship to
EntityB.
My part of the code is as follows.
Whatever I tried at this moment, " java.lang.NullPointerException" at
the first line of the following codes. (aKeyOfEntityA.relations()
doesn't return any records)
In the next page, there is no WODisplayGroup. I used to bind
aKeyOfEntityA.relations to
the list of WORepetition and this shows a list of related EntityB
records.
Any help would be very much appreciated.
NSArray anArray = new NSArray(aKeyOfEntityA.relations());
EOSortOrdering so1 = EOSortOrdering.sortOrderingWithKey("ep_date",
EOSortOrdering.CompareAscending);
EOSortOrdering so2 =EOSortOrdering.sortOrderingWithKey("ep_Category",
EOSortOrdering.CompareAscending);
NSArray soList = new NSArray(new Object[]{so1, so2});
sortResult = EOSortOrdering.sortedArrayUsingKeyOrderArray(anArray,
soList);
