Hey David

Hope this post winds up at the right place.

I set up a delegate class and made a rule for it. I set the rule priority very high.

what is your rule?

priority: 110 LHS: pageConfiguration = 'QuerySchoolAdmin' RHS: queryDataSourceDelegate RHS Value: "pc2master.app.delegates.SchoolAdminQueryDataSourceDelegate" Assignment: ERDDelayedObjectCreationAssignment

I am using the NavigationController and navigation.plist from the ERModern example. Heavily modified.

That should be fine.

The navigation tab calls the NavigationController WOComponent for the query which returns queryPageForEntityName(SCHOOL_ADMIN)

You might want to try a named page configuration to limit the impact of your changes in testing.

public WOComponent queryDocumentAction() {
ERD2WQueryPage page = (ERD2WQueryPage) D2W.factory().pageForConfigurationNamed("QuerySchoolAdmin", session());
...
}

Prior to including the delegate class the QueryPage for the Entity was controlled by a rule which limited the query criteria.

What was that rule? Did it work? Why did you decide not to use the rule?

I am still using the rule below
priority: 100 LHS: (pageConfiguration = 'QueryEmbeddedSchoolAdmin' or pageConfiguration = 'QuerySchoolAdmin') RHS: displayPropertyKeys RHS Value: ("firstName", "lastName", "adminType", "email", "isActive", "schools.name") Assignment: com.webobjects.directtoweb.Assignment

After the inclusion of the delegate class the Query page includes all the criteria ie. the controlling rules no longer fire or have the desired effect.

Not sure why this is happening.

This also affects All the query pages launched from the navigation tabs for all the entities.

Definitely not sure why this is happening. Sounds like a problem with the scope of your rule(s)

When the find is initiated-- the datasource is not modified as per the delegate class -- it doesn't seem to be called.

In the delegate class I put the following qualifierFromSenderMethod.

  private EOQualifier qualifierFromSender(ERD2WQueryPage sender) {
   NSMutableArray<Object> args = new NSMutableArray<Object>();
   args.addObject(((Session)session()).schoolBoard().boardName());
   args.addObject(((Session)session()).school().name());
EOQualifier qual = (EOQualifier.qualifierWithQualifierFormat( " schoolBoard.boardName = %@ and schools.name = %@ ", args));
ERXAndQualifier finalQual1 = new ERXAndQualifier(new NSArray<EOQualifier>(qual, sender.qualifier()));
  return finalQual1;
}

the code below assumes the use of the Wonder templates for EOGenerate

  private EOQualifier qualifierFromSender(ERD2WQueryPage sender) {
SchoolBoard sb = (((Session)session()).schoolBoard());
    School aSchool = (((Session)session()).school());
EOQualifier q = School_Admin.SCHOOLBOARD.eq(sb).and(School_Admin.SCHOOLS.eq(aSchool)).and(sender.qualifier());
  return q;
}

I couldn't seem to get your suggestion to get happy so I formulated the above to combine the two qualifiers.
Any help much appreciated.

Paul
