I'm facing one (hopefully) last problem now: When I try to activate a data node (or even an empty folder in the data JCR Browser) I get the following error message:

"Can't activate: : 1 error detected:
Message received from subscriber: Activation failed | /sbkv: mandatory property {http://www.jcp.org/jcr/1.0}uuid does not exist on web8081"

I again thought that this would be due to a missing "mix:referencable" on the web8081 instance, but that's not the case. The two instances now have the exact same customnodes.xml file and I'm still getting the error message. Then I thought that the data nodes on the author instance might be missing the uuids, so I deleted them all and created new test nodes using the gui: still no success in activating them.

Any help is warmly appreciated since I wanted to have this running yesterday evening... Thanks!

I see, you found the solution yourself. I wanted to test few different
scenarios before responding to you, but seem you managed to figure it
out yourself in the mean time :)
By adding mix:referencable you do not loose performance. The reason why you have to do it is the fact that this mixin is no longer implied since
we do not add mix:versionable to all nodes by default.

I added "mix:referenceable" as supertype to "dataBase". This solved
the problem. Of course I don't know if I'm loosing performance
benefits again this way...

O.k., after some digging around I had a closer look at the
custom_nodetypes.xml file and compared the two from Mag 3.5.4 and
3.6 M1. The only remarkable difference I could find is in the
definition of mgnl:contentNode. The Mag 3.6 file lists
mix:referencable as supertype for this type together with
nt:hierarchyNode. The old one only lists nt:hierarchyNode as
supertype. Now I vaguely remember something about a change in
nodetype definitions in Mag 3.6 to improve performance. Could it be
that nt:hierarchyNode used to have mix:referencable as supertype and
now doesn't anymore?

If so I guess this would mean that I have to add mix:referencable as
supertype to my data nodes. Should I add it to each one? Or should I
add it to one of their common supertypes? Which one: dataItem,
dataItemBase, dataBase?

Hm... I thought about this too, because I imported the config from
the old installation instead of creating it with the UI. So as last
test before I posted this question I removed the config (/modules/
data/config/types/mynode, /modules/data/trees/mynode), all data and
recreated it using the GUI... but also the same name. Do you think
that this might be the problem? Where are the node type definitions
being stored? And how would I add mix:referencable to it?

Thanks for the help!

Hi Will,
is that from a data type you defined yourself manually or via
DataModule
UI? If it is the former, then you need to make sure that you add
mix:referencable to it, if the latter it is most likely a bug.

I'm testing Magnolia 3.6 M1 with a site which uses the data module. I'm pretty happy with the speed, but I'm facing a show stopper now.
The following code works fine on Magnolia 3.5.4 but throws an
exception in 3.6m1

The code:

          Content itemValues = (Content) matching.next();
          String itemValuesUUID = itemValues.getUUID();

The exception:

javax.jcr.UnsupportedRepositoryOperationException
  at org.apache.jackrabbit.core.NodeImpl.getUUID(NodeImpl.java:
2830)
  at
info .magnolia.cms.core.DefaultContent.getUUID(DefaultContent.java:
897)

Additional info: The "itemValues" node which is causing the above
is a
data module node so it has its own nodetype.

Any ideas anyone? Thanks!

Will
