Variables into 'Multiple Selection Widget'

Dear all,

I am developing a (hopefully) interactive dashboard on KNIME 5.8.1. LTS for later deployment on the Business Hub as Data App.

The use case is rather simple, I have a lot of biological activity data which is classified in 4 categories.

| Active       |
| Inconclusive |
| Probe        |
| Unspecified  |

For visualisation, I want the user to be able to select one or more classifications to focus on.

However, using ‘Table Row to Variable’ as suggested by K-AI, leads to only one value of the 4 values being propagated.

I tried ‘Table Column to Variable’ with the same result. What I’d need is to configure these nodes so they output a String Array as Flow Variable so that all options are available in the Multiple Select Widget.

Any way to do that? Any suggestions?

Thanks a lot for your help!

Joachim
