[TYPO3-dev] TYPO3 7.0.2: Cannot connect to signalSlot [SOLVED]

[Thomas Hucke]

Hi Helmut,

thank you for your help.
Your response was one part of the solution.

The other one is that I had to copy the signalSlotActionMethod of 
TYPO3\CMS\Extbase\Mvc\Controller\ActionController to my own controller:
/**
  * Emits a signal before the current action is called
  *
  * @param array $preparedArguments
  */
protected function emitBeforeCallActionMethodSignal(array 
$preparedArguments) {
  $this->signalSlotDispatcher->dispatch(__CLASS__, 'beforeCallActionMethod', 
array(get_class($this), $this->actionMethodName, $preparedArguments));
}

Passing __CLASS__ to the dispatcher always sends 
'TYPO3\CMS\Extbase\Mvc\Controller\ActionController'. So I had either 
register my handler to the ActionController - which I would not like to - or 
I copied the whole method to my controller. Doing so __CLASS__ passes the 
classname of my controller to the dispatcher.

Just if one got a similar question....


Take care
Thomas

Just use:

$signalSlotDispatcher =
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\SignalSlot\\Dispatcher');


Kind regards,
Helmut
