+            unique reference (or no reference) set.<br/>
+            Products with a default_code of '/' or empty will automatically be assigned a code of "!!DP!!" followed

+            Otherwise the setting of the unique constraint will fail and the module will fail to install.<br/>

+            When u create a product(not product template) with attribute, It would delete the first product, which
