I'm continuously getting the error: Drupal\Core\Config\Schema\SchemaIncompleteException: Incomplete or missing schema for mymodule.myentity.myentityname in Drupal\Core\Config\Entity\ConfigEntityBase->toArray() (line 248 of core/lib/Drupal/Core/Config/Entity/ConfigEntityBase.php).

Here is how I'd implemented the EntityForm:

class MymoduleForm extends EntityForm {
  public function form(array $form, array &$form_state) {
    $form = parent::form($form, $form_state);
    $entity = $form_state['entity'] = $this->getEntity();
    $form['name'] = array(
      '#type' => 'textfield',
      '#title' => t('Name'),
      '#default_value' => empty($entity->name) ? '' : $entity->name,
      '#required' => TRUE,

    return $form;
  public function validate(array $form, array &$form_state) {
    parent::validate($form, $form_state);
    $entity = $this->getEntity();
    //perform validation
  public function save(array $form, array &$form_state) {
    $entity = $this->getEntity();
    //throws error here

    $edit_link = \Drupal::linkGenerator()->generateFromUrl($this->t('Edit'), $this->entity->urlInfo());

Doing a print_r($entity) shows two Object results: one showing all the values I'd filed up in the form and the other completely emplty.

That error has nothing to do with your form.

You need to provide a config schema for your config entity, see examples in node.schema.yml and many other places.

See also the configuration schema documetation.

Could provide an example? or a Tutorial link? I'm quite new to D8. – xan Jul 6 '14 at 13:41
@con_28 Giving a specific example isn't really possible as we don't know what fields your entity has. D8 is in alpha, so tutorials will be hard to come by. See node.type.* in core/modules/node/config/schema/node.schema.yml, comment.type.* in core/modules/comment/config/schema/comment.schema.yml for examples, after reading the docs Berdir linked to – Clive Jul 6 '14 at 14:18
Oh wait, there's a fully-fledged config entity example in the Examples module, that should show you what's needed – Clive Jul 6 '14 at 14:21
@Clive: Thankyou. That was helpful. – xan Jul 6 '14 at 14:52
