Hey Ramsey,
I'm using the branch delegate in other places where the user is given a choice
of what the next page should be, but I thought that since I'm figuring it out
on-the-fly during the request that nextPageDelegate was the way to go. I've
revised my NPD and here's what it looks like now:
public WOComponent nextPage(WOComponent sender) {
WOComponent nextPage;
if (((ERD2WQueryPage) sender).queryDataSource()
.fetchObjects()
.count() == 1) {
InspectPageInterface ipi =
D2W.factory().inspectPageForEntityNamed(Student.ENTITY_NAME, sender.session());
((ERD2WInspectPage) ipi).setObject((Student) ((ERD2WQueryPage)
sender).queryDataSource().fetchObjects().lastObject());
nextPage = (WOComponent) ipi;
} else {
nextPage = ((ERD2WQueryPage) sender).nextPage();
}
return nextPage;
}
