     gwt_domain_service.findall(new asynccallback<list<gwtdomain>>() {                  @override                 public void onfailure(throwable caught) {                     exitmessage = msgs.dialogaddpermissionerrordomains(caught.getlocalizedmessage());                     exitstatus = false;                     hide();                 }                  @override                 public void onsuccess(list<gwtdomain> result) {                        (final gwtdomain gwtdomain : result) {                         gwt_domain_service.findactionsbydomainname(gwtdomain.name(), new asynccallback<list<gwtaction>>() {                              @override                             public void onfailure(throwable caught) {                                 exitmessage = msgs.dialogaddpermissionerroractions(caught.getlocalizedmessage());                                 exitstatus = false;                                 hide();                             }                              @override                             public void onsuccess(list<gwtaction> result) {                                  (gwtaction gwtaction : result) {                                 rootcheckbox= new checkbox();                                 rootcheckbox.setboxlabel(gwtdomain.tostring());                                     treeitemcheckox = new checkbox();                                      roottreeitem = new treeitem(rootcheckbox);                                     treeitem =  new treeitem(treeitemcheckox);                                     treeitemcheckox.setboxlabel(gwtaction.tostring());                                     roottreeitem.additem(treeitem);                                  }                                 tree.additem(roottreeitem);     }                     });  }
