I created a custom Type that has a UserPart attached to it.
According to this issue on GitHub you can't add a CommonPart to content that also has a UserPart because it causes a StackOverflowException but I would still like items of my custom Type to show up in the content list. I already store CreatedUtc and PublishedUtc in the custom PartRecord, can I manually plug these in somewhere?
EDIT: For clarification, my specific scenario is that I am building a public facing Orchard website based on existing data that was used in a private application up to this point. I have a legacy table with user accounts that need to be mapped to Orchard Users but they also represent travel agencies that visitors should be able to browse and that Orchard admins should easily be able to edit and create through the Dashboard. I got the idea to create a TravelAgency type with a UserPart from Sipke's webshop tutorial
Content Types do not require to have a CommonPart to show in the Content List. If i remember properly its done by triggering the Creatable() in your migrations. Also if you have a UserPart, you could Lazy loaded or just reference it via Foreign Key.
Why would you like something like that to be part of the Content List? I usually keep my business-specific Content Types tucked away in a nice section, so there are easier to visualise and use for users.
There is definitely a bug but as they comment you could extend taxonomies to accomplish your task and keep in mind sometimes changing the Orchard Codebase might fit your purposes, you only have to keep track of your changes when you upgrade next time. I have done it a couple of occasions to fit my projects.
If i remember properly, its been a while.. If you look in the core code where the Content List is created it looks for Creatable() Types. digging even more inside the code, chances are the Query in charge will join the CommonPart, hence your problem. You could easily add another query in the controller and add whatever you are after. The problem though, will be refactoring the rest of actions to accommodate your your type too. Way easier isolating your new Type. had to look at it for you, check this baby: Orchard.Core.Contents.Controllers.AdminController
