[TYPO3-mvc] Copy object and add to repository

FYI: We're currently discussing this use case in the Extbase team and 
probably consider the current behavior as a bug/missing feature. We 
didn't come to a final decision yet on what to do and how to implement 
this, but I'll keep you updated. In the meantime I'd suggest to create a 
new Object and fill it using a loop like this:

$availableProperties = 
Tx_Extbase_Reflection_ObjectAccess::getGettablePropertyNames($product);
$newProduct = $this->objectManager->create('Tx_..._Product');

foreach ($availableProperties as $propertyName) {
	if (Tx_Extbase_Reflection_ObjectAccess::isPropertySettable($newProduct, 
$propertyName) && !in_array($propertyName, array('uid','pid'))) {
		$propertyValue = 
Tx_Extbase_Reflection_ObjectAccess::getProperty($product, $propertyName);
		Tx_Extbase_Reflection_ObjectAccess::setProperty($newProduct, 
$propertyName, $propertyValue);
	}
}


This is a code snipped I use to map properties from one object to 
another one, not necessarily of the same type. That's why there is some 
overhead with "isPropertySettable" etc.
