For example you might want to call it adminHomePage(). That just doesn't matter.

Try something like
D2WPage page = (D2WPage)D2W.factory().defaultPage(session());
D2WContext c = page.d2wContext();
EODatabaseDataSource ds = new EODatabaseDataSource(session().defaultEditingContext(), c.entity().name());
page.setDataSource(ds);
return page;

All it did was check which component was loaded as currentPage, and load that into the wrapper's content area. Obviously not appropriate in this case. I changed it to just return a WOActionResults which is an instance of Admin.

If it doesn't work, then we'll know you've done something wrong with your setup. All the navigation actions called in the ERModernMoviesDemo NavigationMenu.plist are routed through this controller. If you want a much more detailed look at things that are possible, check out the Factory class in the BugTracker application.

Instead of it opening inside your AUC, why don't you have the admin link open up a nice full page completely outside your current pagewrapper with the unchanged ERModernLook all ready to go?

Then the D2W rule system will find the pagewrapper, menuheader and skin framework required to make the complete page. Part of your navigation strategy on the Admin/D2W side will need to include a link back to reload the "normal" page wrapper.

It is very simple, I have a header, sidebar navigation, and an AjaxUpdateContainer which changes based on what link the user clicks on the navigation sidebar. One of these links is the Admin link, which will (I hope) cause the D2W stuff to be loaded into the AjaxUpdateContainer, without disturbing anything else.
