Needing a starting point to understand how traversal and acquisition work, would you give me some hints to solve the type of problem below ? In this example company, a subsidiary must establish proposal based on a product list. If it doesn't have products, it must use the headquarter's ones. 1 with this hierarchy, how can i reach the Product list in the Products Folder from Proposal 1 of Subsidiary 1 ? 2 If Products weren't folder but objects and items weren't contained objects but properties of Products, would the solution be the same ? Root/Headquarter | |-- Products (Folder) | | | | | --- item 1 (objects) | --- item 2 '' | --- item 3 '' | | | | | |-- Proposals (Folder) | | | | | --- Proposal x (object) | |---Subsidiary 1---- | | | |-- Products (Folder) | | | --- no objects | | | | | |-- Proposals (Folder) | | | | | --- Proposal 1 (object) v -- Andre PZP Enthusiast
