If I wan't to publish a report to the JRS the new dialog shows me all used resources (subreport, images, translation).
In this dialog I can decide as well, if the resouce is ignored or overwritten, ...
In case of overwriting the local resource is uploaded. That is working fine all the time.
If the resource is not in the same folder as the report. The replacement of the Expression (which is also shown in a extra column) doesn't work.
