Refresh Widget

KNIME Analytics Platform
1

Hi,

the Refresh Widget is really a very cool add-on to KNIME.

But… nevertheless I would like to ask for an additional feature…

I am working on a multi-page app using KNIME Analytics and it would be highly desirable to have the option to hide the Refresh Button of a dedicated page via a flow variable (like this is the case for other widgets).

What do you think?

Best regards

Jürgen

Hey Jürgen,

what exactly is the use case you are trying to solve with this?

Hi Daniel,

We have an old KNIME workflow dealing with Labview TDMS files.
I am looking for possibilities to create a new, more user friendly app.
And of course I would like to stay with KNIME.
The multi page approach seems to be appropriate as we have to

Choose the tdms file(s) for import
Select the tdms groups
Select the set of variables stored in the selected groups
Import the files according to the chosen groups and variables
Show the data in interactive plots (scatter and box plots)
And create last but not least a pdf report with the BIRT engine

For every step (=page) a dedicated Refresh Button is (might be) needed as one Refresh Button would implicate to restart the process. This restart is not desirable as e.g. the import has to be done in Python and takes quite some time.

Is the workflow idea clearly described?

Any ideas to have several Refresh Buttons but only one visible?

Thank you very much in advance

Jürgen

Hey Jürgen,

nice to hear that you want to stick with KNIME.
Regarding the workflow I still don’t entirely get what you want to achieve with the multiple refresh buttons, but only one is visible. Maybe I am missing something. The way it already works is, that you only see the refresh button that is part of the current page (component). So once you switch a page you will not see the refresh button of the old page, but just the one from the new page. Also this refresh button will then only trigger a re-execution for everything that is downstream of this particular refresh button node and not the whole workflow.

Greetings,
Daniel

Hi Daniel,

I will try to go this path and will come back to you with my experiences.

Thank you and have a nice weekend

Jürgen
