AngularJS directive with a Swiffy instance throws error on route navigation -

-

setup

i have directive takes path json file attribute value, loads json, instantiates swiffy:

angular.module('myapp')   .directive('swiffy', function ($http) {     return {       restrict: 'a',       scope: {},       link: function postlink($scope, $element, attrs) {          var stage;           // listen angular destroy         $scope.$on('$destroy', function() {            if(stage) {             stage.destroy();             stage = null;           }         });           // load swiffy json         $http({           method: 'get',           url: attrs.swiffy         }).success(function(data, status, headers, config) {            stage = new swiffy.stage( $element[0], data );           stage.start();          }).error(function(data, status, headers, config) {          });       }     };   });

the markup:

<div swiffy="my-animation.json"></div>

i have basic routing setup:

angular   .module('myapp', [     'ngcookies',     'ngresource',     'ngsanitize',     'ngroute'   ])   .config(function ($routeprovider) {     $routeprovider       .when('/', {         templateurl: 'views/main.html',         controller: 'mainctrl'       })       .when('/info', {         templateurl: 'views/info.html',         controller: 'infoctrl'       })       .otherwise({         redirectto: '/'       });   });

the controllers here empty.

problem

the json file loads should , swiffy svg created fine. when navigate away view has swiffy directive, angular throws error , whole app breaks:

typeerror: cannot read property '1' of null     @ annotate (angular.js:3179:24)     @ object.invoke (angular.js:3846:21)     @ angular.js:5580:43     @ array.foreach (native)     @ foreach (angular.js:323:11)     @ object.<anonymous> (angular.js:5578:13)     @ object.invoke (angular.js:3869:17)     @ angular.js:3711:37     @ object.getservice [as get] (angular.js:3832:39)     @ adddirective (angular.js:6631:51)

the error thrown after '$destroy' event has triggered in directive, know stage.destroy() has run on swiffy object.

the angularjs function throws error can found here https://github.com/angular/bower-angular/blob/7ae38b4a0cfced157e3486a0d6e2d299601723bb/angular.js#l3179

as far can tell, annotate() trying read parameters on anonymous function , fails. have no errors if remove swiffy instantiation errors have result of creating swiffy object.

i'm using:

so far i've tried:

  • updating angularjs version 1.2.17-build.111+sha.19d7a12. (it contains update annotate function doesn't fix problem)
  • removed 'strict mode' directive.
  • removed stage.destroy()

i'd rather not make changes angular.js source (i tried make angular skip anonymous functions broke more things) , swiffy runtime not available un-minified i'm not sure going on in there. ideas great, thanks.

probably little late answer, try upgrading angularjs 1.3 or higher. there blog post problems angularjs 1.2 , svg here:

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
