PowerBI custom visual live data

Hi everybody,

I have a problem with the development of a custom visual that relies on automatically updated datasets in Power BI web. 

To a specific dataset data is pushed every second and the visual should display it in the dashboard and update itself when new data arrives. With the new development tools (the integrated development visual) everything works perfect and the way I want it to work. But when I package the visual into a .pbix (with the pbiviz tool) and import it in PowerBI Web, the only data which is shown on the dashboard is the data which has arrieved before the visual got active. The strange thing is that the update method is called everytime and only when new data is pushed to the dataset but the VisualUpdateOptions given to the update method doesn't contain any new data just the old ones.

I would really appreciate if someone has an idea how I can solve this problem!

Thx in advance

Jakob
