As the 'documents' app is closed source, the only easy way to customize its use is to use studio.
But the lack of documentation makes it difficult.
I checked the configuration setting to have document workspace for products.
And now documents uploaded in chatter of a product or products template are available in the documents app.
But i would like to add a tab to my product page with a list(tree) view with all documents related to this product. To make them more accessible/sortable/filterable than there in the chatter.
I thought it would be enought to just set res_id equal to active_id but that does not seem to be the case.
Anyone has any clues ?
