        $scope.asyncData = asyncData;
        $scope.moreData = syncData;

        $scope.save = function() {
            $uibModalInstance.close($scope.theThingIWantToSave);
        };

        $scope.cancel = function() {
            $uibModalInstance.dismiss('cancel');

})();

Hi, never mind, having read the documentation properly! the $uibModal.open() call returns a promise 'opened' which will be rejected if any of the resolve cases fail e.g.
$uibModal.open({
animation: true,
template: modalTemplate,
controller: ModalInstanceController,
resolve: {
syncData: () => syncData,
asyncData: () => someWebServices.getAsyncData()
}
}).opened.then(
function (success) {},
function (error) {
console.log('ui failed to open, reason : ', error);
}
);

This way you can detect a resolve error and present the details to the user.

This code doesn't work :(

asyncData: () => someWebServices.getAsyncData() gives error:

JS_Parse_Error
"Unexpected token: punc ())"
