Extend ‘ProductList.Item.Model’ and update the create function. when we add items to wish list a record is created in product list items,after creating the record we will get a internal id of the created record. So we can use ‘nlapiSubmitField’ to set value in custom field.
For eg- We have Brand,Product category field in product list item record we need to concatenate these 2 field to another fields ‘Sort’.
so using a saved search with the internal id we got the values of Brand and product category. Then we concatenate these values and set using ‘nlapiSubmitField’.
