Wie kann ich eine bestehende Prozess Variable in einem embedded form anzeigen?

Answer 1

<script cam-script type="text/form-script">
    camForm.on('form-loaded', function() {
        camForm.variableManager.fetchVariable('fooBar');
    });
    camForm.on('variables-fetched', function() {
        $scope.fooBar = camForm.variableManager.variable('fooBar').value;
    });
</script>

{{fooBar}}
