Variables into 'Multiple Selection Widget'

[Jo1607]

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

Hi @Jo1607 / Joachim

In this wf Variables into Multiple Selection Widget.knwf (62.1 KB) your input categories are aggregated as a Set. The set is used as as a flow variable in the Multiple Selection Widget.
