File-Download Widget - download from website not possible

Hello everybody,

I’ve build an simple workflow and want that the user is possible to download the final file from the KNIME server website with just “one click”. There are no needed inputs within the workflow.
The file location will be saved in a string.

Here is a screenshot of my workflow:

If i start the workflow from the website it simply says “workflow executed successfully”. But there is no download or save file button.
Are the nodes in the right order?
I have tested it without the “logic” metanode but it also doesn’t worked.

Can you help me build my workflow? :slight_smile:

Best regards

Hi @Carfisch,

I assume that you’re trying to run this workflow on the WebPortal? If yes, there’s two things to consider here:

  1. Based on your screenshot, the workflow is in executed state. On the WebPortal, workflows are run from the state in which they are saved. I.e., if you try to run it like that, it will already be executed. Solution is to reset the workflow and then save it.
  2. For the File Download to appear, it has to be in a component/wrapped metanode as well. The content of each component is rendered as one page on the WebPortal.

Hope that helps :slight_smile:
