Symfony Configuration Parsing

Question

I have the following configuration on my config.yml

ci_api:
    file:
        purposes:
            attachment:

And my configuration class looks like this:

    $treeBuilder = new TreeBuilder();
    $rootNode = $treeBuilder->root('ci_api');

    $rootNode
        ->children()
            ->arrayNode('file')
                ->children()
                    ->arrayNode('purposes')
                        ->children()

                        ->end()
                    ->end()
                ->end()
            ->end()
        ->end(); //children

    return $treeBuilder;

When i tried to run this it gets an error saying:

Unrecognized option "attachment" under "ci_api.file.purposes"

Note that under purposes there can be indefinite number of children.

Thanks.

Simply add the prototype definition as array on the last element definition as follow:

$rootNode
    ->children()
        ->arrayNode('file')
            ->children()
                ->arrayNode('purposes')
                    ->prototype('array')  // Add this line
                    ->children()

                    ->end()
                ->end()
            ->end()
        ->end()
    ->end(); //children
