Placeless documents (like stored renditions) shouldn't crash the JSF web UI. At least the following cases must be treated:
- putting in trash through trash service
- UI redirection after delete
- URL generation
When putting in trash, as there is no natural "trash container" from which to un-trash, we'll do an immediate delete.
For URL generation an id-based pattern must be used, as a path doesn't make sense.
Placeless documents like persited renditions can now be browsed in the JSF UI without any crash.
