Simone Tripodi updated SLING-6324:
----------------------------------
Attachment: SLING-6324.patch
hi there [~teofili],
the issue is in the fact that the {{ResourceDistributionPackage}} does not have
a unique identifier - resource path is good to identify a unique resource, but
multiple packages can be built on top of the same resource and they need to be
identified by an unique id.
The proposed attached patch try to solve the issue by assigning a unique UUIDs
to each {{DistributionPackage}}
As usual, I am open to suggestions in order to improve the qualify of my
contributions, TIA! :)
