Hello Klas,
Thank you for your support.
It is working when setting default value for the Article ID field to 0.
I can't make it work with live value.
Article ID is used in many other fields, I hope this setting will not broke anything else.
I would like to notice that this default value can be overriden in a Seblod list menu: typing a space in Article ID field and I get back all my products (don't know if it is logical).
I find it very interresting because I can manage many display fo list products with only one list (no duplication of lists, more concistancy in list template…).
Regards
