Hello everybody,
I have a problem when retrieving childnodes from a frozen node. When I first
add the childnodes and then make a checkin with the parent node, everything is
fine. When I then checkout the parent node, change something on the childnodes
and checkin the parent again, I get ItemNotFoundExceptions when trying to read
something (propertys or childnodes) from the second version of the frozen
parent node.
Caused by: javax.jcr.ItemNotFoundException: failed to build path of
72530f73-9d5d-4a2b-832a-0109320b95dc: 0f1ecab6-c3a8-436a-b66e-648b29e661ad has
no child entry for 72530f73-9d5d-4a2b-832a-0109320b95dc

This is basically the main code I want to run:
Node elementNode =
session.getNodeByUUID(entity.getUuid());
if (elementNode == null) {
return null;
}
VersionHistory history = elementNode.getVersionHistory();
VersionIterator it = history.getAllVersions();
//Skip RootVersion
it.skip(1);
while(it.hasNext()) {
Version version = it.nextVersion();
NodeIterator nodeIterator =
version.getNodes("jcr:frozenNode");
ContentMapper contentMapper = cmf.createInstance(qType);
while (nodeIterator.hasNext()) {
Node node = nodeIterator.nextNode();
jcrElements.add(contentMapper.map(node,
ContentLoading.NONE));
}
}
The ContentMappers make something similiar to the OCM Framework – they convert
jcrnodes to business entities. When I try to access child informations in the
last expression, the exception above is thrown. This is only the case with the
second version of the elementNode (that is after first checkingout the version
after the rootVersionNode).
The code for saving the second version is the following:
node.checkout();
saveAttributes(node, businessEntity);
mergeAssociations(session, node, businesEntity);
node.save();
node.checkin();
Any advices?
Best Regards
Stephan Eichmann
