Characteristic fileds hidden if they have no value

Thank you for your help on an earlier post, here's another problem I am having

I've imported my products from virtuemart and have found that the parent / child product relationship is maintained in that, if I add some characteristics to my parent product and click on "Manage Variants" I can see all my imported child products listed (capture4.jpg).

However if I click on one of the variants to edit it, the characteristics fields aren't displayed. I guess this is because they don't have a value set (see capture5.jpg). Is it possible to display the assigned characteristics so that they can be selected?

Many thanks,

Ian

I've done that Nicolas, they display for auto generated variants but not for the imported ones. Any other ideas?

Thanks,

Ian

Thanks for your reply. Being pig-headed I wasn't going to accept the variants shouldn't be there, so after manually creating characteristics in Hikashop I found that by changing the variant product_type in the 'hikashop_product' table from "main" to "variant" I was able to see and edit the characteristics for the imported child products without having to delete and recreate them.

This is the query I used against the database ...

UPDATE `ap_hikashop_product` SET `product_type` = 'variant' WHERE `product_parent_id` > 0
