Removing a version
Hi,
I'm trying to remove a version of a Node, but the
VersionHistory.removeVersion() method throws :
javax.jcr.ReferentialIntegrityException: Unable to remove version. At
least once referenced..
Secton 8.2.2.10 (Removal of Versions) of the specification indicates that
the version graph should be automatically repaired upon removal. Then,
VersionHistory.removeVersion() should take care of references. In fact, a
user cannot alter the references (jcr:predecessors and jcr:successors),
since they are protected properties.
Here's the example :
Node root1 = session.getRootNode() ;
Node test1 = root1.addNode(test) ;
test1.addMixin(mix:versionable);
test1.setProperty(test, 1);
session.save();
test1.checkin();
test1.checkout();
test1.setProperty(test, 2);
session.save();
test1.checkin();
test1.checkout();
test1.setProperty(test, 3);
session.save();
test1.checkin();
VersionHistory vh = test1.getVersionHistory();
for (VersionIterator vi = vh.getAllVersions(); vi.hasNext(); ) {
Version currenVersion = vi.nextVersion();
String versionName = currenVersion.getName();
if (!versionName.equals(jcr:rootVersion)) {
String propertyValue =
currenVersion.getNode(jcr:frozenNode).getProperty(test).getString();
System.out.println(Removing version : + versionName +
with value: + propertyValue);
vh.removeVersion(versionName);
}
}
Something I do wrong ?
Many thanks,
Nicolas
Re: Removing a version
Hi,
I have already verified that.
The error is for removal of version name : 1.0 and the base version name
is 1.2.
I've updated the example to make sure it never tries to remove the base
version :
Node root1 = session.getRootNode() ;
Node test1 = root1.addNode(test) ;
test1.addMixin(mix:versionable);
test1.setProperty(test, 1);
session.save();
test1.checkin();
test1.checkout();
test1.setProperty(test, 2);
session.save();
test1.checkin();
test1.checkout();
test1.setProperty(test, 3);
session.save();
test1.checkin();
String baseVersion = test1.getBaseVersion().getName();
System.out.println(Base version name: + baseVersion);
VersionHistory vh = test1.getVersionHistory();
for (VersionIterator vi = vh.getAllVersions(); vi.hasNext(); ) {
Version currenVersion = vi.nextVersion();
String versionName = currenVersion.getName();
if (!versionName.equals(jcr:rootVersion)
!versionName.equals(baseVersion)) {
String propertyValue =
currenVersion.getNode(jcr:frozenNode).getProperty(test).getString();
System.out.println(Removing version : + versionName +
with value: + propertyValue);
vh.removeVersion(versionName);
}
}
Thanks,
Nicolas

Hi Nicolas,
I didn't try your code but I think it throws
ReferentialIntegrityException because you are trying to remove the
base version which is referenced by the versioned node.
see http://thread.gmane.org/gmane.comp.apache.jackrabbit.devel/3746

Re: Removing a version
hi nicolas,
this is probably a bug in jackrabbit. thank you for reporting it. can
you please file a jira issue
(http://issues.apache.org/jira/browse/JCR) for this? thanks.
