PropertyList Beta Code - Unable to use
Hi,
It could be that you have some console errors in your browser. Could you check this?
And you could also check if you registered Property Definition Type:
[PropertyDefinitionTypePlugIn]public class ContactListProperty : PropertyListBase<SliderImage>{ }

It appears that I am getting an error in the Console. Wish I'd checked that earlier. I do have the Property Definition Type Set Correctly.
"Unable to load /EPiServer/shell/Stores/metadata/gjcity16.Models.Properties.SliderImage?dojo.preventCache=1450969461665 status: 500"

Alright, I figured it out. Turns out I was using an incompatable Content Type. I appreciate all of your help. As it turns out, you apparently can't use Url in a PropertyList.

This topic was created over six months ago and has been resolved. If you have a similar question, please create a new topic and refer to this one.
I've just followed the blog post to enable a PropertyList. I know it's beta code but it appears to work for others. I'm having a bit of an issue when it comes to doing anything with it. In the images in the blogs I've seen there is a button with a plus sign below it to add a new Item to the List. This is what I'm seeing. Does anyone know what I've done wrong?
[EditorDescriptor(EditorDescriptorType = typeof (CollectionEditorDescriptor))] Images { get; set; }
public virtual IList
