File Download Widget

Hi!

I am creating a WF for the Webportal on KNIME 4.3 and the newest Server Version.

I have a loop which creates datasets and saves them. Therefore I created a temporary folder on the server Mountpoint. I am feeding the “path” type flow variable to the “csv writer” node, I also connected the “File Download Widget” to the CSV Writer node and configured it with the new “path” type flow variable (referencing to the previously created folder with the datasets). The File Download Node gives a warning “Connection Type is not yet supported” and is not able to execute.

How do I use the File Download Widget with the new File handling?

Best solution would be: Download of the folder all the datasets are saved at via the GUI of the WebPortal.

PS: sdf writer nodes do not support the new “path” file handling.

Hello @FabianK,

We haven’t been able to recreate the “Connection Type is not yet supported” message.

There is a test WF on the Hub from Christian Stohr (AP_testing_upload-download-widget – KNIME Hub) that demonstrates usage of the File Download Widget with both path and string flow variables, so it should work. It is not yet clear why it doesn’t, in your example.

It would be best if you could provide a reproducible sample workflow that demonstrates the issue, then we could work with a developer to determine the root cause.

Please let us know if you would be able to provide an example workflow.

Thank you,
Nickolaus

Hey @FabianK ,

i’ve got the same issue with the File Download Widget but only incase i use the server mountpoint as destination. When i use local filesystem it works for me. Did you find a solution yet?

Hi there,

Can you clarify your situation/use-case, configuration requirements, and any results/error messages?

For example, you say ‘I’ve got the same issue with the FDW’ - is it giving you the same “Connection Type is not yet supported” message?
What does your workflow look like?
Are you able to provide a sample workflow that demonstrates the issue?

Regards,
Nickolaus
