Hi! I built a few ordinary CMS sites in Umb 6/7 the past 2 years, simple ones with docTypes and Templates with basic addressing content pages of docType to iterate childrens as lists, navbars and content. Often just by using the editors inside Umbraco.

Now I am developing and mulit-lingual site with shared root content :

www
    -- se
    ---- Produkter
    -- en
    ---- Products
ProductDatabase
    -- Categories
    ---- IndustriPC
    ------ Panel PC
    ------ Box PC
    -- Products
    -- Filters
    -- Manufacturers

The Produkter/Products, doctype: ProductStart, has an contentPicker which I set to below ProductDatabase>Categories

The site will have a shared node we call "Product Database".

The problem now, how can I fix som the category node Panel PC under the en node of the site get URL like below?

/en/products/industripc/boxpc

I am currently playing with UrlProvider and ContentFinder but when the UrlProvider kicks in and I try to get the Url I want to change the W3P process crashes in IIS. I compile the project to an IIS 7.5 (Win2008R2 server).

Note: If I change the content.Url to content.Parent.Url it seems to work but I have no use of that, just tried to see.

The UrlProvider code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Threading.Tasks;
using extend.logic.Utilities;
using Umbraco.Web;
using Umbraco.Web.Routing;

namespace extend.logic.UrlProvider
{
    public class CategoryUrlProvider : BaseClass, IUrlProvider
    {
        public string GetUrl(UmbracoContext umbracoContext, int id, Uri current, UrlProviderMode mode)
        {

            var content = umbracoContext.ContentCache.GetById(id);

            if (content != null && content.DocumentTypeAlias == "dtCategory")
            {

                var url = content.Url;

                return url;

            }
            return null;
        }

        public IEnumerable<string> GetOtherUrls(UmbracoContext umbracoContext, int id, Uri current)
        {
            return Enumerable.Empty<string>();
        }
    }
}

I register it with

namespace extend.logic.Events
{
    public class UmbracoEvents : ApplicationEventHandler
    {
        protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {

            UrlProviderResolver.Current.InsertTypeBefore<DefaultUrlProvider, CategoryUrlProvider>();

        }
    }
}

Am I on the right track here? What is the best practise when you want to create a "BackOffice Admin Database" and then "pull" the data from the actual site/CMS to display it, and have the correct inherited urls as a combination of the CMS page and the BackOffice node.

Anyone know if theres a complete kit to download, source code and all that I may study and understand how to do this.

Feels I am walking in circles.
