I am trying to override the checkQuoteItemQty method in cateloginvetory/item. I want to send more detailed errors.
I tried copying the file to my local while keeping the same structur local/mage/cateloginvetory/model/item.php that didn’t work.
I the tried creating a new directory in local mycompany/cataloginventory/model/item.php. I enabled the new module and created a config.xml to rewrite model. But that also didnt work.
Attached are the xml files.
What am I doing wrong?
