I'm getting this error when trying to view a Sitecore item based on a template that contains nothing but one sublayout played in a placeholder in another layout. I can place the sublayout in other sublayouts and view it on another item, and I can preview the item, but when I go to view that item I get this:
The layout for the requested document was not found.
[blah blah blah]
Requested Layout: {00000000-0000-0000-0000-000000000000}
[blah blah blah some more]
The only way I've found to view the new item is to do a "Publish Site" from the Publish tab. Is there a way to get that one item working without republishing everything?
