I am trying to relate two objects in a many-to-many, I used EOModeler
which seemed to do everything like it is in my other projects which
have successful many-to-many's.
EOModeler created a join table with the two primary keys of the
objects to be related and the relationships to the other tables.
I turned on SQL logging, etc.

Exception occurred while handling request:

[com.webobjects.eoaccess.EOGeneralAdaptorException] null: An
exception was thrown when trying to delete a transaction.
<WorkerThread4> com.webobjects.foundation.NSForwardException for

nformationAdded(EODatabaseContext.java:4685)
at com.webobjects.eoaccess.EODatabaseContext.performChanges
(EODatabaseContext.java:6393)
My code looks like:
public WOComponent registerChanges() {
java.util.Enumeration enumerator = allFriends.displayedObjects
().objectEnumerator();
while ( enumerator.hasMoreElements() ) {
Friends nextFriend = (Friends)enumerator.nextElement();
if ( nextFriend.inAttendance && ! nextFriend.editAttendance )
{ // remove attendee
...
} else if ( nextFriend.editAttendance && !
nextFriend.inAttendance ) { // new attendee
nextFriend.addObjectToBothSidesOfRelationshipWithKey
( registerForEvent, "InEvents" );
registerForEvent.addObjectToBothSidesOfRelationshipWithKey
( nextFriend, "friendss" );
nextFriend.inAttendance = true;
}
}
try {
_Utilities.eoSaveChanges( session ); // throws exception
I have 2 public booleans in the Friends EOGenericRecord sub-class
which are used for the WOCheckBoxes in the WORepetition. All the
displaying and clicking seems to work fine and the one friend in the
list who attends the event is picked up by the loop.
Why is it saying in the log "An exception was thrown when trying to
delete a transaction."
<deleteObject> is not being called.
It should create a join record in the join table and alter the in-
memory arrays of the Friends EO and the InEvents EO.
