spring - Managed beans with custom ViewScope -

i'm doing web application using spring 3.1.0.release, jsf 2.x, jpa 2 hibernate provider. use prettyfaces 3.3.2 friendly url. application run on tomcat 6.35 .

i wanted use jsf viewscope decided follow implementation found on web : http://comdynamics.net/blog/109/spring3-jsf2-view-scope/

public class viewscope implements scope {      private static final logger logger = loggerfactory.getlogger(viewscope.class);      @override     public object get(string name, objectfactory objectfactory) {         final map<string, object> viewmap = facescontext.getcurrentinstance().getviewroot().getviewmap();          object instance = viewmap.get(name);         if (instance == null) {             instance = objectfactory.getobject();             viewmap.put(name, instance);         }         return instance;     }      @override     public object remove(string name) {         logger.debug("viewscope::remove {}", name);         return facescontext.getcurrentinstance().getviewroot().getviewmap().remove(name);     }      @override     public string getconversationid() {         return null;     }      @override     public void registerdestructioncallback(string name, runnable callback) {         //not supported     }      @override     public object resolvecontextualobject(string key) {         return null;     } } 

i notice @predestroy not called on them show question @predestroy never called on @viewscoped.

does mean managed beans viewscope never destruct ? conduct memory leak. should use scope so?

it's happen custom viewscope on spring or on mojarra ?

thanks.

problem incorrect implementaiton of view scope. creates spring bean objectfactory.getobject(); never destroy it.

to solve - check correct implementation support registerdestructioncallback.

bwt, current mojjara implementation not call @predestory on bean too. free bean instance @ least.
