Re: Removing a version

[Edgar Poce <ed...@gmail.com>]

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

[Nicolas Belisle <Ni...@bibl.ulaval.ca>]

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
