angularjs - Non-Flickering Polling in Angular with REST Backend -


i managed getting constant polling of backend functional using this answer.

but on every timeout ui flickering (empty model short time). how can update model (and view respectively) after new data arrived in order avoid flickering effect?

here current controller (slightly modified step_11 (angular.js tutorial)):

function mypollingctrl($scope, $routeparams, $timeout, model) {  (function tick() {     $scope.line = model.get({         modelid : $routeparams.modelid     }, function(model) {         $timeout(tick, 2000);     }); })();  }

// edit: i'm using current stable 1.0.6 of angular.js

try updating data in success callback. this:

(function tick() {     model.get({         modelid : $routeparams.modelid     }, function(model) {         $scope.line = model;             $timeout(tick, 2000);     }); })();

this should prevent flicker occurring when $scope.line empty model resource fetching data.

Eclipse formatter for java ending braces -

i know if it's possible setup eclipse format braces using banner style. we're working code uses banner style formatting , keep consistent within team version control reasons. here's example of banner style formatting not familiar: public class foo { //------------------------ public static void main (string[] args) { boolean condition = true; try { if (condition) { system.out.println ("condition true"); } else system.out.println ("not condition"); } catch (exception ex) { // handle errors } } //------------------------ } update: name style ratliff. experiment java->code style->formatter preferences. "banner style" seems poor use of space given outline view , quick outline functionality.

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
