String List/PropertyStringList

I keep having problems to use the property String List/PropertyStringList in the alloy project.

I've installed Alloy two times and I get an error message each time I edit the custom property type String List/Propertytype.

Is there some kind of configuration to use this property before viewing the settings for this property? I haven't used this property before, so I could use some information in how to use this property.

I'm doing a tutorial using Alloy and have a pagetype where this property is required to have value, but when I'm creating a new instance of the pagetype using this property, no fields is showing to enter value.

I do I make PropertyStringList work?

Error message is:

Well, I managed to resolve my problem here.

The answer here is ambiguous. First of all I'm new to Episerver CMS 7 so I'm not so familiar with all the new stuff.

But the reason why I didn't manage to create a new Product page was because of the property uniqueSellingpoints which was required for the page to be created.
I started on a empty project where I added code when I needed it in my project. So I was missing the directory called Business and ClientResouces in the Alloy project. That's why I wasn't able to se the control to initialize the required fields. Uniquesellingpoints control was missing because of ClientResources wasn't added to the project.

UniqueSellingPoints is based on the property called String List which doesn't have a Legacy rendering this causes a bug when you try to view the settings for this property in admin mode. It also causes a bug if you try to create a page with String List in the old edit mode.

All new pages should use the new onPage-editing function. Here Uniquesellingpoints is showing without bugs.
