First thing to do is double check which methods you've overridden in
your outline configuration, as well as if you've replaced the
content or label providers. The default content and label providers
rely on the IJFaceNodeAdapters, and they're ultimately responsible
for updating the content viewer. Replacing the provider entirely
would remove this update notification.

It would work, but the mechanism of using an adapter that's
listening for changes lets us refresh just the section of the DOM
that's been changed ().
You should look at
org.eclipse.wst.xml.ui.internal.contentoutline.JFaceNodeCont entProvider.inputChanged(Viewer,
Object, Object) for an example of how to install your own adapter
factory when the viewer input is changed, and then create an adapter
of your own to do the same. Your adapter wouldn't have to handle
the content and label provider responsibilities, but please don't
replace the existing IJFaceNodeAdapter and factory as they are
required to keep the Design page up to date in the same way.
