Hi,

My page has a bunch of categories that are very specific, and I'd like to categorize them programatically by adding an category when they are published, depending on what category the editor has selected. In this specific case the editor has selected the page to have the category "Air Max" and I want to add the category called "Shoes" to the page when the editor publishes. So i've made an IInitializableModule that I cant get to work. The big issue is the CreateWriteableClone part on the PublishedContent event, take a look;

namespace MyWebsite.Business.Initialization
{
    [InitializableModule]
    [ModuleDependency(typeof(global::EPiServer.Web.InitializationModule))]
    public class PublishedContentCategoryInitialization : IInitializableModule
    {
        private IContentEvents _contentEvents;
        public void Initialize(InitializationEngine context)
        {
            if (_contentEvents == null)
            {
                _contentEvents = ServiceLocator.Current.GetInstance();
            }
 
            _contentEvents.PublishedContent += contentEvents_PublishedContent;
        }
 
        public void contentEvents_PublishedContent(object sender, ContentEventArgs e)
        {
            if (e.Content is MySpecificPage)
            {
                var contentLoader = ServiceLocator.Current.GetInstance();
                var contentrepository = ServiceLocator.Current.GetInstance();
                var myspecificpage = contentLoader.Get(e.Content.ContentLink);
                if (myspecificpage != null)
                {
                    var clonedpage = myspecificpage.CreateWritableClone();
                    var categoryrepository = ServiceLocator.Current.GetInstance();
                    var categoryList = CreateCategoryList(myspecificpage.Category, categoryrepository);
 
                    var locator = ServiceLocator.Current.GetInstance();
                    var rootCategory = locator.GetRoot();
                    CategoryCollection childCategories = rootCategory.Categories;
                    var catlist = new List();
                    foreach (Category category in childCategories)
                    {
                        catlist.Add(category);
                    }
 
                    if (categoryList.Any(x => x.LocalizedDescription == "Air Max"))
                    {
                        var shoecategory = categoryrepository.Get("Shoes");
                        page.Category.Add(shoecategory.ID);
                    }

                  contentrepository.Save(page, SaveAction.Publish, AccessLevel.NoAccess);
                }
            }
        }
 
        private List CreateCategoryList(CategoryList myspecificpagecategories, CategoryRepository categoryrepository)
        {
            var categoryList = new List();
            foreach (int catId in myspecificpagecategories)
            {
                Category category = categoryrepository.Get(catId);
                categoryList.Add(category);
            }
 
            return categoryList;
        }
 
        public void Preload(string[] parameters) { }
 
        public void Uninitialize(InitializationEngine context)
        {
            if (_contentEvents == null)
            {
                _contentEvents = ServiceLocator.Current.GetInstance();
            }
 
            _contentEvents.PublishedContent -= contentEvents_PublishedContent;
        }
    }
}

The Category gets added, but I always end up in an infinite loop of publishing and publishing and publishing.. Has anyone solved this issue in a better way, like adding a category to a page programatically on publish? Im running latest version of EPi btw. 

Thanks!
