Quickforms within Loops

Dear KNIME Team,

I am trying to get user data within a loop structure to create a kind of wizard depending on previously parsed data. While using the workflow (on KNIME 3.5.2) I can input data once while requesting user information within the loop.

I attached a simplified example with and without a wrapped meta node. Maybe it will work well on the server version, which I cannot test right now.

Best regards,

Hi Stephan,

To ask for user input multiple times, try encapsulating the content of the loop in a wrapped metanode. Then a new page will open on a webportal as many times as defined in a loop start node.
Please see the workflow attached.
