Auto Version for WEM 8.5

Victor_Prasad

Hello,

How do I set autoversioning on for WEM 8.5.  Content changes keep getting made, then reverted.  I would rather just revert to an old versoin.  However, it seems one has to save a version first, then make content changes. 

Anyway to force it to autoversion?

Thanks,

Mr. V

Hi Victor, yes you can associate an Auto Versioning class to the Content Instance Update and Create Events... Here's a simple example that you can compile, jar, deploy, and register (details of this are in the management SDK Dev Guide). The Event you should use is PrePersistenceUpdate and PrePersistenceCreate. Another approach is to use similar code in a Program Task and version the content as part of workflow.

package com.vignette.training.autoversion;

import com.vignette.as.client.common.ref.ManagedObjectVCMRef;
import com.vignette.as.client.common.AttributeData;
import com.vignette.as.client.exception.*;
import com.vignette.as.client.javabean.ContentInstance;
import com.vignette.as.client.javabean.ContentManagementOps;
import com.vignette.as.client.javabean.ManagedObject;
import com.vignette.as.config.ConfigUtil;
import com.vignette.as.server.event.AsEvent;
import com.vignette.as.server.event.AsPrePersistenceEvent;
import com.vignette.as.server.event.IAsEventListener;
import com.vignette.logging.Category;
import java.util.Date;

public class VersioningPrePersistenceEventListener implements IAsEventListener
{

    private static final Category logger;

    public VersioningPrePersistenceEventListener()
    {
    }

    public int getPriority()
    {
        return MEDIUM_PRIORITY;
    }

    public void consume(AsEvent asEvent)
        throws ApplicationException, AuthorizationException, ValidationException
    {
        ManagedObject mo = null;
        AsPrePersistenceEvent ppe = null;
        ContentInstance ci = null;
        AttributeData ad = null;

        try
        {
            logger.debug("=== VersioningPrePersistenceEventListener......");
            logger.debug("consume:  " + asEvent.getClass().getName());
            logger.debug("consume:  " + asEvent.getType());

            if(asEvent instanceof AsPrePersistenceEvent)
            {
                ppe = (AsPrePersistenceEvent)asEvent;
                mo = ppe.getManagedObject();
                if(mo instanceof ContentInstance)
                {
                    ci = (ContentInstance)mo;
                    logger.debug("consume: ci.name:  " + ci.getName());
                    Date date = new Date();
                    String user = ConfigUtil.getAuthzOps().getCurrentUser();
                    ManagedObjectVCMRef vref = new ManagedObjectVCMRef(ci);
                    int versionNumber = ContentManagementOps.createVersion(vref, "Version created on " + date.toString() + " by " + user);
                    ContentManagementOps.addLabelToVersion(vref, versionNumber, "Auto " + date.toString());
                }
            }
        }
        catch(Exception e)
        {
            logger.debug("Exception while processing content: " + e.getMessage());
        }
    }

    static
    {
        logger = Category.getInstance(VersioningPrePersistenceEventListener.class);
    }
}
