Ok.. I'll try this for the thumbnail..
About D2W...
I have something like
Product <-->> ERAttachment for a photos property.
But.. i watched the tutorial of David and he created a many-to-many, so
Product <-->> ProductPhotos <<--> ERAttachment
Product has a "photos" property (so a NSArray of ERAttachment).
But.. I don't know how to manage this with the rules, both on Inspect and on Edit/Create configuration.
BTW: how can I select the first object of an array with a rule?
What I want to do is:
In ListProduct configuration I want to display the thumbnail
In Edit/Create Product configuration I want to display all the photos in "maximum" size (i don't know yet the size.. I'll decide later)
Thanks again for your answers
Francesco
