Major Description
We mount some pages dynamically, using different thread than wicket filter. Our extension tracks service registry and once it finds something it calls application instance to mount new page. To don't use ThreadLocals we keep application assigned to private field. It worked well with Wicket 1.4.x.
public final class PageMounterTracker extends ServiceTracker { private final WebApplication application; @Override public final Object addingService(ServiceReference reference) { PageMounter mounter = (PageMounter) super.addingService(reference); List<MountPointInfo> infos = mounter.getMountPoints(); for (MountPointInfo info : infos) { application.unmount(info.getPath()); application.mountPage(info.getPath(), info.getPage()); } return mounter; } @Override public final void removedService(ServiceReference reference, Object mounter) { PageMounter pageMounter = (PageMounter) mounter; List<MountPointInfo> infos = pageMounter.getMountPoints(); for (MountPointInfo info : infos) { application.unmount(info.getPath()); } super.removedService(reference, pageMounter); } }
