[TYPO3-mvc] Signal/Slot pattern

[Henjo Hoeksma]

Hi Tobias,

good you got it working. Please realize t3lib_div::makeInstance is
deprecated notation, you should use the objectManager (as you tried)
nowadays like so:

$signalSlotDispatcher = $this->objectManager->get('Tx_**
Extbase_SignalSlot_Dispatcher'**);

Kind regards,

Henjo

Problems are small because we learned how to deal with them.
Problems are big because we need to learn how to deal with them.
