KNIME AP 5.8.2 Modern UI — Can we replace the node configuration dialog with an external Chromium window on Configure click?

Node Development

Hello everyone,

We are developing a custom node on KNIME Analytics Platform 5.8.2 with Modern UI.

Requirement:

  • When the user clicks the node’s “Configuration” / Configure button,

  • we want to prevent the default configuration dialog from opening,

  • and instead open an external URL on a different domain in a separate Chromium-based window (or external browser window).

Questions:

  1. Is there any supported way to intercept the Configure action and replace the default dialog with a custom action?

  2. If not, what is the recommended UX pattern in Modern UI to guide users to an external portal/config page?
    (For example: a minimal node dialog that shows a button “Open external configuration portal”.)

We appreciate any pointers (extension points, APIs, sample code, or KNIME team guidance).

Thanks!

Are you using the Python Extension Development API?

If yes, you could try to omit all configure parameters from the node (or set them to hidden to enable assigning values to them) and instead open the separate windows in the configure() method of the node.
