Why all child checkBoxes are not checked when user immediately click on root checkbox(GWT)?

I am developing a GWT app and I use Tree, TreeItem and CheckBoxes. I have treeItem with one rootcheckBox(allCheckBox) and when user clicks on that treeItem, that expands to child treeitems with checkBoxes(rootCheckBox) which also have child treeItems in them(childTreeItemCheckox). I have set that, when user clicks on allCheckBox all his child checkboxes(rootcheckboxes) are checked. But I notice bug: When I open Form Panel and immediately select allCheckBox not every rootCheckBox is checked, 2 or 3 last rootcheckboxes stay unchecked. I think that is because when user immediately click on allCheckBox not every rootCheckBox is retrieved from onSuccess method. This is my code:

 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) {

                for (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) {
                            checkedItems = new GwtCheckedItems();
                            checkedItems.setName(gwtDomain);
                            rootCheckBox = new CheckBox();
                            rootCheckBox.setBoxLabel(gwtDomain.toString());
                            listCheckBoxes.add(rootCheckBox);

                            rootTreeItem = new TreeItem(rootCheckBox);
                            for (Map.Entry<GwtCheckedItems, CheckBox> map : listOfNewClass.entrySet()) {
                                boolean checking = true;
                                if (!map.getValue().getValue()) {
                                    checking = false;
                                    break;
                                }
                                checkingAllCheckBox = checking;
                            }
                            childCheckBoxMapList = new HashMap<GwtAction, CheckBox>();
                            checkedItems.setMap(childCheckBoxMapList);
                            for (GwtAccessPermission gwtAccessPermission : checkedPermissionsList) {
                                if (gwtAccessPermission.getPermissionDomain().toString().equals(checkedItems.getName().toString())) {
                                    if (gwtAccessPermission.getPermissionAction().toString().equals(GwtAction.ALL.toString())) {
                                        rootCheckBox.setValue(true);
                                    }
                                }

                            for (final GwtAction gwtAction : result) {

                                final CheckBox childTreeItemCheckox = new CheckBox();

                                allTreeItem.addItem(rootTreeItem);
                                childCheckBoxMapList.put(gwtAction, childTreeItemCheckox);

                                        if (!child.getValue()) {

                    }
                });


            }

        });

        permissionFormPanel.add(tree);

 Could someone help me to solve this bug? Thanks in advance.
