Encountering Error in Angularjs : [ngTransclude:orphan] Illegal use of ngTransclude directive in the template -


i got piece of code directive inside directive: 

<script>  app.directive('testchart', function () {             return {                 restrict: 'e',                 transclude: true,                 controlleras: 'chartctrl',                 template: '<div><ng-transclude></ng-transclude></div>',                 controller: ['$scope', '$element', '$attrs', '$compile', function chartcontroller($scope, $element, $attrs, $compile) {                     $scope.chartid = $scope.$id;                     let content = angular.element('<div><div id="container'+ $scope.chartid + '"></div></div>');                     $element.append(content);                     $compile($element.contents())($scope); //<---- recompilation                      var html = $element.html();                     var hc = highcharts.chart('container' + $scope.chartid, {                      });                 }]             };         })       </script>

when adding template: <ng-transclude></ng-transclude> template error: error: [ngtransclude:orphan] illegal use of ngtransclude directive in template! no parent directive requires transclusion found.

what's cause of error? i've looked through other questions same problem unable apply solutions problem.

recompilation line in testchart directive causing problem. before execution of line angular created (& compiled) testchart directive as:

<div ng-transclude=""></div>

later on appending element & compiling treats simple div element having ng-transclude directive, default showing orphan ngtransclude directive error. so, remove line directive definition, , else working fine. directive definition (same excluding recompilation line)

app.directive('testchart', function() {   return {     restrict: 'e',     transclude: true,     controlleras: 'chartctrl',     template: '<div><ng-transclude></ng-transclude></div>',     controller: ['$scope', '$element', '$attrs', '$compile', function chartcontroller($scope, $element, $attrs, $compile) {        $scope.chartid = $scope.$id;       let content = angular.element('<div><div id="container' + $scope.chartid + '"></div></div>');       $element.append(content);       //$compile($element.contents())($scope); //<---- recompilation        var html = $element.html();       console.log(html);       var hc = highcharts.chart('container' + $scope.chartid, {        });     }]   };  })

working plunker

in cases you'll need compulsory compilation, before appending directive template here ng-transclude used.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
