Yes, I just didn't paste the rest of the class. Here it is in its entirety:
package com.k12.totalview.ui.delegates;
import com.webobjects.appserver.WOComponent;
import com.webobjects.directtoweb.D2W;
import com.webobjects.directtoweb.InspectPageInterface;
import com.webobjects.directtoweb.NextPageDelegate;
import com.webobjects.eocontrol.EOEnterpriseObject;
import er.directtoweb.pages.ERD2WInspectPage;
import er.directtoweb.pages.ERD2WQueryPage;
public class QueryToListOrInspectNextPageDelegate implements NextPageDelegate {
public WOComponent nextPage(WOComponent sender) {
WOComponent nextPage;
if (((ERD2WQueryPage) sender).queryDataSource()
.fetchObjects()
.count() == 1) {
EOEnterpriseObject eo = (EOEnterpriseObject) ((ERD2WQueryPage)
sender).queryDataSource()
.fetchObjects()
.lastObject();
InspectPageInterface ipi = D2W.factory()
.inspectPageForEntityNamed(eo.entityName(),
sender.session());
((ERD2WInspectPage) ipi).setObject(eo);
nextPage = (WOComponent) ipi;
} else {
nextPage = ((ERD2WQueryPage) sender).nextPage();
}
return nextPage;
}
}
