Sounds like a bug. I'll look into it. > Also I understood that my approach isn't very effective so I'll use > the many-to-one relation of Product object in order to add one more > product for given vendor: > my $product = Product->new; > $product->vendor($vendor); # $vendor ISA 'Vendor' > $product->save(); If you just want to add to a one-to-many related list, you should use the "add_on_save" method. Continuing to use the tutorial example, it will be named add_products(): $vendor->add_products(Product->new); $vendor->save(); That will just add the new product, rather than deleting them all and then re-saving the entire list. You should only set products() when you really want to replace the entire list. (Of course, I still have to fix that bug to make that part work... :) -John ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
