Bug in UI - Collected data is not shown

[PVahldiek]

After setting up the initial datasource and pipeline from the example, there is no output displayed on the UI with the collected data.
If you click on the link with above, you can see that the data is actually collected but not displayed. So it seems to be an error in the UI:
