    <p>I was reading the documentation on defining forms as services and followed the guide. but I keep running into the following error:</p> <blockquote> <p>Could not load type "submission"</p> </blockquote> <p>here is my <code>services.yml</code></p> <pre><code>services: submission.form.type.submission: class:Awesome\SubmissionBundle\Form\Type\SubmissionType tags: - {name: form.type, alias: submission} </code></pre> <p>here is my form</p> <pre><code>&lt;?php namespace Awesome\SubmissionBundle\Form\Type; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\OptionsResolver\OptionsResolverInterface; class SubmissionType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder -&gt;add('contact', 'text') -&gt;add('message', 'textarea') -&gt;add('submit', 'submit') ; } public function getName() { return 'submission'; } public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver-&gt;setDefaults(array( 'data_class' =&gt; 'Awesome\SubmissionBundle\Entity\Submission', )); } } </code></pre> <p>In any controller I can <code>$this-&gt;get('submission.form.type.submission')</code> without errors.</p> <p><strong>But why can't I do <code>$this-&gt;createForm('submission', $submission)</code></strong> ? as is dictated by the official <a href="http://symfony.com/doc/current/book/forms.html#defining-your-forms-as-services" rel="nofollow">documentation</a>.</p> <p><strong>UPDATE</strong> I have made some progress. I found that if I put my services configuration in symfony's main <code>config.yml</code> rather than the bundles <code>services.yml</code> The code starts to work. This is perplexing but I guess it leads to me posting just how I'm loading the bundle's <code>services.yml</code>.</p> <p>Here is my bundle's registered compiler pass:</p> <pre><code>&lt;?php namespace Awesome\SubmissionBundle\DependencyInjection\Compiler; use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface; use Symfony\Component\DependencyInjection\ContainerBuilder; use Symfony\Component\Config\FileLocator; use Symfony\Component\DependencyInjection\Loader\YamlFileLoader; class SubmissionCompilerPass implements CompilerPassInterface { public function process(ContainerBuilder $container) { $relative_path = DIRECTORY_SEPARATOR . implode(DIRECTORY_SEPARATOR, array('..', '..', 'Resources', 'config')); $loader = new YamlFileLoader($container, new FileLocator(__DIR__ . $relative_path)); $loader-&gt;load('services.yml'); } } </code></pre> <p>and regardless of where I place my configuration the command <code>container:debug submission.form.type.submission</code> always gives the same output which seems fine to me:</p> <pre><code>[container] Information for service submission.form.type.submission Service Id submission.form.type.submission Class Awesome\SubmissionBundle\Form\Type\SubmissionType Tags - form.type (alias: submission) Scope container Public yes Synthetic no Required File - </code></pre>

    1. COThe mismatch in namespaces is a copy/paste/edit failure of yours, right? The class namespace `Awesome\SubmissionBundle\Form\Type;` does not match `Guide\SubmissionBundle\Form\Type\SubmissionType` in your service definition. Did you clear your cache?

    3. COI have edited the code in your question. please make sure you have no tabs in your code. Further i recommend you stick to the symfony2 [coding standards](http://symfony.com/doc/current/contributing/code/standards.html) i.e. for method declarations. Does `this->createForm($this->get('submission.form.type.submission'), $submission);` work?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
