When I download the latest 1.26.4 release of OpenUI5 http://sap.github.io/openui5/download.html and look at the "Application Best Practices" demo. It does not entirely work due to some 404 errors when retrieving some important json data.
The Application Best Practices demo also throws 404s on SAPs own site https://sapui5.netweaver.ondemand.com/sdk/test-resources/sap/m/demokit/tdg/index.html?responderOn=true#/Products%283%29/category
See your console.
It finds "Product.json" but not "Products.json"... "Category.json" but not "Categories.json"... etc.

Whats wrong? How do I fix this?
