Getting cq:lastReplicationAction value after Page deletion.

Hello,

I have created AEM page. At this time, there will not be any entry for cq:lastReplicationAction. I have created ReplicationEventHandler that will trigger during page activation, deactivation, deletion time.  

Now, I have 2 scenario's.  1: Page is deleted before any publishing the page (Not even published single time) .  2:  Page is deleted After publishing earlier. 

Now, I have deleted this page. When I Read the "cq:lastReplicationAction" from page Properties in my ReplicationEventHandler  file, for both scenario's it gives me: "Delete" . Actually, for the 1st scenario I was expecting null and for the 2nd scenario I was expecting some value, since that page is published earlier.

 

Thanks in advance.

Hi @mahesh_gunaje, Actually, EventHandler gets triggered after the event occurs, so by that time the "cq:lastReplicationAction" property value is already assigned.

In your case, you need to use a preprocessor to process the replication action before it happens.

Here is an example for your convenience:

@Component(
        service = Preprocessor.class,
        immediate = true,
        property = {Constants.SERVICE_RANKING + ":Integer=1"}
)
public class ReplicationPreprocessor implements Preprocessor {
    
    @Reference
    private ResourceResolverFactory resourceResolverFactory;

    @Override
    public void preprocess(ReplicationAction action, ReplicationOptions options) {
        ResourceResolver resourceResolver = resourceResolverFactory.getThreadResourceResolver();
        PageManager pageManager;

        if (resourceResolver != null) {
            pageManager = resourceResolver.adaptTo(PageManager.class);

            if (pageManager != null) {
                Page currentPage = pageManager.getPage(action.getPath());
     
                if(currentPage != null) {
                    ValueMap properties = currentPage.getProperties();
                    String lastReplicationAction = properties.get("cq:lastReplicationAction", "");
                    // Work with this 'lastReplicationAction' value
                }
            }
        }
    }
}

 

Let me know if this works for you.
Thanks

Hi @mahesh_gunaje 
When you delete the page(using UI or pageMagaer api), the page is unpublished automatically , so you don't need to explicitly write any event listener to listen delete/unpublish events.
