Interactivity Value Filter Widget node is not working, string specs is not define

[hueyyng]

Hello,

Is anyone have a problem with the Interactivity Value Filter Widget node? This has been bothering me for quite some weeks already, the filter widget will show empty regardless the node itself or inside a component, it seems like the node not able to read the string category.

When I check on the input flow, this is what I found.
I actually have data but the string spec doesn’t recognize it, what mistake did I have made and how can I solve this?

Regards,

Hello @hueyyng,

if you check node’s description you’ll find following:
“Note that the filter uses the possible values set on a nominal column’s domain as configuration. To ensure the values are reflected and sorted correctly the Domain Calculator and/or Edit Nominal Domain nodes can be used beforehand.”

What does that actually means check here:

Nominal Value Row Filter - Issue on limitation of values

Hi, I can’t look at your workflow since I am on mobile, but the problem should be easy to fix. Generally KNIME stores possible values of nominal columns, but only up to 60 unique values. If there are more, possible values are not stored. In the domain calculator under possible values you can specify in the bottom left, if my memory serves me right, how many values values should be stored. This overwrites the maximum of 60 for the table coming into the domain calculator. So just change that valu…

Hope this helps!
