Associated mandatory fields

So, this is a new feature i'm developing. Basically, the product i'm working now has a huge ... HUGE amount of attributes and it's easy for the user to try publish a product and several validation errors appear since there are various associated attributes that need to be filled, depending on some field options.

So we developed a easy way to access and fill out associated information that's mandatory. When an attribute that has associated mandatory information is selected a pop-up shows to give the user the possibility to fill out all the associated information. This way he's always focused on the same type of information and he understands the scope of information he's typing.
