PathNotFoundException when copying between workspaces
Hi
as mentioned before, I get a PathNotfoundException
when I try to copy a node from one workspace to
another. Here is the programme excecution:
1. Open session sA with workspace wA
2. Create a new node nA in workspace wA
3. Call sA.save() (afterwards it reports no pending changes)
4. Open session sB with workspace wB
5. Call wB.copy(wA, nA, [dstPath])
6. A PathNotFoundException is thrown
Funny thing is, that when I restart the repository
instance after node creation, this procedure works.
Thanks for sheding light on this

Thanks a lot! It works now ...
Obviously, by registering the repository twice with
RegistryHelper.registerRepository two separate repository
instances were created (and I set overwrite to true
so no NameAlreadyBoundException was thrown :-/

hi felix,
my guess is that you somehow have 2 different Repository instances
that were created using identical configurations, i.e. they are
reading from/writing to
the same physical storage. this setup is not supported and will lead to
corrupt data.

Hi Stefan
i tracked it down to the HierarchyManagerImpl class. There,
resolvePath() [199] is called for the source path (e.g. '/site/test',
where 'test' is a newly added or copied node).
The execution path is as follows:
[199] resolvePath(Path path)
[222] for (...)
[iterate over all path elements]
[226] parentState.hasChildNodeEntry(...) => false for name='test'
[241] parentState.hasProperty(...) => false for name='test'
[253] PathNotFoundException
Actually, the NodeState.ChildNodeEntries of 'site's parentState
does not reflect the newly added node.
Unfortunately, I can't reproduce it with a simple setup for
now ...
As said before, after a restart of the repository after adding
the node, it can be copied without a problem (with same code
sequence!!).
Regards,
Felix

i tested what you're describing with the following code fragment:
Session sA = r.login(new SimpleCredentials("johndoe",
"".toCharArray()), "A");
Session sB = r.login(new SimpleCredentials("johndoe",
"".toCharArray()), "B");
Node nA = sA.getRootNode().addNode("foo");
sA.save();
Workspace wB = sB.getWorkspace();
wB.copy("A", nA.getPath(), "/bar");
everything worked as expected.
are you sure you're logging in on the same Repository instance?
cheers
