Cloning a tree containing shareable nodes into another workspace throws
ItemExistsException
-------------------------------------------------------------------------------------------
Key: JCR-2473
URL: https://issues.apache.org/jira/browse/JCR-2473
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 2.0-beta6
Reporter: Thomas Draier
There's a problem when trying to clone a tree in another workspace, when this
tree contains shareable nodes.
Let ws1 be one workspace, which contains one node A. This node has two
sub-nodes B and C. B and C share a shareable sub-node D :
A
| \
B C
| |
D D
Let ws2 be a second workspace. Then calling ws2.clone("ws1" , "/A" , "/A" ,
false) throws an ItemExistsException ( copyNodeState line 1628 ) . This is done
when the copyNodeState is checking if the nodeId is already present in the
workspace - which is the case when copying the second instance of the shareable
node. I can't find in the specification something about this case - but it
would be logical to add a share to the node when coming across this situation -
at least in the CLONE ( and probable COPY too ) cases. I don't know what would
be expected in the CLONE_REMOVE_EXISTING case - we might not want to remove the
node if it's shareable, and also add a share here.
I fixed the issue by handling the case the node is shareable in the COPY and
CLONE cases of copyNodeState - you'll find attached the corresponding patch. Do
you think this solution is ok ?
