Hi, Tim, thanks for the reply! I can confirm that I do have a
sitemap.xmap at:
[dspace-src]/dspace/modules/xmlui/src/main/resources/aspects/Trail/
and that its contents look exactly the same as the sample code in your
presentation (Conal Tuohy's Trail aspect, updated for DSpace 1.5).
Here's one thing I think might be causing a wrinkle. We have modified
parts of the dspace-api, in order to apply the Shibboleth patch. Do you
think there would be a conflict in the overlay system if our directory
structure looked like this?
[dspace-src]
dspace/
