Hi, I'd like to ask what is the best way to intercept a delete operation so that I can do some pre-preparation/validation/post-processing before actually letting Post Servlet deleting that node.
So far, I've tried listening to TOPIC_RESOURCE_REMOVED , but when this even is handled, the Node is already removed, so I can't perform anything as it's too late; I can't put my hands on the content that has been deleted. All I found out was the "path" info, but no resource data. Another thing I've tried was to extend SlingPostServlet, but it was a no go, b/c the org.apache.sling.servlets.post.impl.* is a private package, can't be used on other bundles, which makes sense. Another idea I had was to extend SlingAllMethodsServlet, but the problem I'm having is that I'm overriding the default workflow in Sling, which is something I don't want to do. I would not override the default workflow, just because I have a tiny logic to inject before deleting the content. I was thinking to decorate the DeleteOperation, but didn't figure it out if I can/I should. I'm also thinking that I may register a PostProcessor to be called for the DeleteOperation, but I think that it's too late since the content has been already deleted. What would be your approach in this case ? Thanks, Dragos Dascalita Haut
