• extbase extension with controller classes
• flexform with "calling cascade" -> in switchableControllerActions in the itemField are the following settings:
  

  <items type="array">
    <numIndex index="0" type="array">
      <numIndex index="0">Label of Form in Backend</numIndex>
      <numIndex index="1">ControllerA->show;ControllerB->edit</numIndex>
    </numIndex>
  </items>
  

• in my example ControllerB has a detail view of an table entry and is calling by a link of ControllerA (a new user call)
• both controller inherit from ActionController

When I call the following lines, ControllerA gets a result set of pid and uid. But ControllerB gets an empty set.

$cObj = $this->configurationManager->getContentObject();
$resultset = array("uid" => $cObj->data['uid'], "pid" => $cObj->data['pid']);

Is this behavior intended or is it a bug? Does exists a workaround?
