seam2 - Seam - understanding PAGE scope and CONVERSATION scope -


i still confused page , conversation (temp) scope. maybe here. fas know, variables outjected page scope live long user postbacks same page. temporary conversation scope instead survives redirect next page. here little example 2 effects confusing me:

first, component , outjections in conversation scope , tempuser data displayed in jsf page. in save method called jsf-page, injected tempuser null. why?

second, if same change component , @in/@outs scopes page scope, tempuser gets correctly injected on postback - gets not saved, wathever reason, although super.update()-method on userhome gets called. or there problem in using homeentities ways (the idea iwa use them dao wrapper)?

@name("useraction") @scope(scopetype.conversation) public class useraction implements serializable {      private static final long serialversionuid = -4852371546895918692l;       @in(create = true)     private userhome userhome;      @out(scope = scopetype.conversation)         @in(required = false,scope = scopetype.conversation)     user tempuser;      @requestparameter     private long userid;      @factory("tempuser")             public user getuser() {                              if (tempuser == null) {             userhome.setuserid(userid);             tempuser = userhome.getinstance();             userhome.clearinstance();         }         return tempuser;             }      public void save() {             userhome.setinstance(tempuser);              userhome.update();     } }

the xhtml contains a:form with

<a:commandbutton   id="update"   styleclass="button admin"    action="#{useraction.save}"    value="#{messages['user.action.update']}"/>

thanks replies. sorry, if 2 problems in one.
