In joomla3 i Get the actual text 0
In joomla2 i Get null

specifically i have been developing for client a product availability column in notification emails til customers.
in joomla2 this $product->product_availability was NULL when i did a var_dump (when value was set to a single ZERO). other values gave correct text-value.
in joomla3 on the other hand it was a string 0 which is correct
