Subject: Removing a version 
Mime-Version: 1.0
Content-Type: text/plain; charset="us-ascii"; format=flowed

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
