[TYPO3-mvc] Problem getting an instance of an object in controller

[Henjo Hoeksma]

Hi list,

I need to compare a XML posted object to an object in the database.

What I do is something like:

$rep = t3lib_div::makeInstance('Object_Repos');
$objectInDb = $rep->findByProperty('PropertyValue');

So far so good.
But when I want to remove this found object using:

$rep->remove($objectInDb);

this throws an error:

The object given to remove() was not of the type 
(Tx_Ext_Domain_Model_Object) this repository manages.

Is this due to the new inject dependency ?

Thanks for your response!
