Remove the population of $this->source_config from FeedsPlugin.

I have a custom feeds processor, which implements sourceForm() to provide options on how the file will be imported. Unfortunately, the options entered by the user on the import form do not end up in $this->source_config inside of the custom entitySave override.

What I have to do is call $source = feeds_source($this->id); and then I can reference the options under $source->config['MyCustomProcessor']['someoption']

I did this in D6 but this doesn't seem to be working in D7 unless I am doing something wrong. I would think $this->source_config would be populated, but it only contains the defaults that were in sourceDefaults(). So it does know that the processor options and defaults are there, but the user value isn't loaded.

It is however stored correctly in the {feeds_source} table.

class CustomProcessor extends FeedsProcessor {
...

  function sourceForm($source_config) {
    $form = array();

    $form['target'] = array(
      '#title' => 'Target ID',
      '#type' => 'textfield',
    );

    return $form;
  }
...
  protected function entitySave($entity) {
    // Filled
    $source = feeds_source($this->id);
    $source->config['CustomProcessor']['target'];

   // Empty
   $this->source_config['target']
 }
...
}
