jsf 2 - Alternative to Deltaspike Multi-Window Handling in Seam 3 Applikation -

i have problems multi-window handling in appliacation. using conversation scope enable multi window / tab handling in case user opens link (button) in new tab conversation shared between old , new tab.

apache deltaspike has solution (http://deltaspike.apache.org/documentation/#_module_overview) using seam 3 (and jsf 2.1) , don't want migrate deltaspike.

so i'm searching alternative solution without deltaspike or possible use deltaspike , seam 3?

i build solution p:remotecommand , answer: in javascript, how can uniquely identify 1 browser window under same cookiedbased sessionid

i added js template creates unique id each browswer tab stores in window.name. calls p:remotecommand check guid:

$(window).load(function() {     // ----------------------     var guid = function() {         // ------------------         var s4 = function() {             return (math.floor(math.random() * 0x10000 /* 65536 */             ).tostring(16));         };         return (s4() + s4() + "-" + s4() + "-" + s4() + "-" + s4() + "-" + s4() + s4() + s4());     };      if (!window.name.match(/^guid-/)) {         window.name = "guid-" + guid();     }      if ($('#guid_form\\:server_guid').text().length == 0 ||              $('#guid_form\\:server_guid').text() != window.name) {         checkguid([{name:'guid', value:window.name}]);     } }) 

added primefaces remotecommand template called script above.

<h:form id="guid_form">     <h:outputtext value="#{checktabaction.guid}" id="server_guid"/>     <p:remotecommand name="checkguid" actionlistener="#{checktabaction.checkguid}" process="@this" partialsubmit="true" /> </h:form> 

and added check action validateds current browser tab / window comparing guid's:

@conversationscoped @named(value = "checktabaction") public class checktabaction implements serializable {      private static final long serialversionuid = 1l;      @inject     private logger log;      private string guid = null;      public void checkguid() {         map<string, string> params = facescontext.getcurrentinstance().getexternalcontext().getrequestparametermap();         string guid = params.get("guid").tostring();          if (this.guid == null) {             this.guid = guid;         }          if (!stringutils.equals(this.guid, guid)) {             log.info("new tab detected!");             throw new nonexistentconversationexception("new tab detected!");         }     }      public string getguid() {         return guid;     }  }
