[TYPO3-mvc] How to check if object was created ?

[Dawid Pacholczyk]

Thanks for the tip about 
$this->objectManager->get('Tx_Ext_Domain_Model_Foo')

About that obvious if construction its so obvious that I`ve checked it 
my first atempt. i wrote here cause it didn`t work :/

My code looks like this

$temp = $this->findByExtRec($resVal['uid']);
				
				if($temp !== NULL)
					echo "jest<br />";
				else
					echo "nie ma <br />";

It always show "There is" even with empty database !
