Can i intercept the "Versioning On Update Properties" and set a description for that version on java

AlfrescoZZZ — Tue, 22 Nov 2022 11:23:12 GMT

I enabled for one document the property "cm:enableAutoVersionOnUpdateProps=true" and everything works as it should, but is there an "elegant" way to intercept the default versioning call and set a description on the version with a text like "Property X has been changed" ?

I had considered a behavior, but I'm having trouble retrieving the property in edit on the "OnCreateVersion" event.

My own solution, but is not pretty...

	public void onCreateVersionVersionableAspectBehavior(QName classRef, NodeRef versionableNode, Map<String, Serializable> versionProperties, PolicyScope nodeDetails) {
		if(this.enable) {
			//logger.debug("START BEHAVIOUR METHOD '" + this.getClass().getSimpleName()+"' '"+new Object(){}.getClass().getEnclosingMethod().getName()+"'");
			String currentusername = AuthenticationServiceUtilities.getCurrentLoginUsername(serviceRegistry);
			try {
    			// Disable auditable aspect
    			behaviourFilter.disableBehaviour();
			  	// Disable rules
			  	ruleService.disableRules();
				AuthenticationUtil.pushAuthentication();
				AuthenticationUtil.runAs(new AuthenticationUtil.RunAsWork<Void>() {
					@Override
					public Void doWork() throws Exception {
						return TenantUtil.runAsTenant(new TenantUtil.TenantRunAsWork<Void>()

					    			behaviourFilter.disableBehaviour();
								  	// Disable rules
								  	ruleService.disableRules();
								  	
							  		// INIZIO CONTROLLI PRECHECK
