The
MenuComponent parentMenu = repository.getMenu(parent);
caused it. I could see the menus in the defaultRepository, but creating a
new one and setting the displayers didn't populate them for some reason. On
an unrelated note, what could cause submenus from being displayed. I have a
whole bunch of pages that forward to a "query results" page which doesn't
get listed in menu-config.xml. How do I make sure the parent tab is still
highlighted and the submenus get displayed?
Thanks,
Robert
