Hi,
I'm having the exact same problem. Did you ever find a solution to this ?
Se my reply in http://world.episerver.com/forum/developer-forum/-Episerver-75-CMS/Thread-Container/2016/7/content-provider---problems-with-edit-ui for a solution/workaround to this.
Hi. I've been away on holiday so I haven't had the chance to reply. I guess you have found the answer. I fixed the problem by inheriting from MediaComponent instead of ComponentDefinitionBase (and remebering to set the repository key by updating "repositoryKey" and not adding it). But I see now that this wasn't the actual fix. By chance I also changed the repository key to lower case which fits the thread you are linking to.
I'm working on a project that has a lot of content folders in a hierarchy that makes it a bit diffucult to navigate. My idea is to add a new navigation pane, as Episerver.Forms does, to the asset widget. For this purpose I've created a IContentRepositoryDescriptor:
and a Component:
The contents of the asset folder returned as root won't load however. Can anybody spot the problem?
