Unanswered: Implement own TreeStore with static and dynamic data
I try to display a TreePanel in my Viewport with a dynamic and static part. For example I have below the root-node different projects which is a dynamic collection as json on my server with a project model. Below each project are three nodes which are static. That means "Stakeholder analysis", "Risk analysis" and "Project targets". Below these static nodes are a flexible number of documents which are represented by each Model for each of the three nodes.
How can I realize that?
