@Georg25: You are welcome!
And for others struggling with the same question, perhaps a single figure says more that thousand words:
- You cannot access data from the server side memory (global/flow/...) in the AngularJS dashboard.
- You can access data from an input message in the AngularJS dashboard frontend. Indeed the msg data is (automatically) transmitted to the node's AngularJs scope object, where the client side code of the UI widget can get it (to update the content or layout of the visible widget).
