Hi Can someone please help with the error attached when I use the column expression node. Do I need to install something around Java?
Thanks,

Can you post the script that is producing the error? If possible, a workflow with some example data would be best so others can try to reproduce the issue.
Thank you so much. I was able to download the zip file and install regarding my other request.
Please find attached the code and error snip. I get the same error when I write any Java script in Column Expression node.
Thanks,
Akash.
Hmmm. I’m not able to reproduce your error so far - the workflow is running fine for me.
Could you upload the relevant portion of the knime.log file? Also, what operating system and version of KNIME are you using?
Hi @akngnew -
In KNIME 4.6, the configuration dialog on the Column Expressions node should have an “Advanced” tab present, but in your screenshot it doesn’t. I wonder if something went wrong during the update process?
Would it be possible for you to try a fresh install of 4.6.1 and see if that resolves the problem?
Hi Scott,
I installed version 4.6.1 but advance tab is still not there and same error in column expression. I have to do the installation through the zip file as my organization doesn’t allow me to install Knime as a normal installation. Is there an update I am missing, if you have the zip file for this?. Thanks Akash.
Hi @akngnew -
Are you sure you did a fresh install? Meaning, download the latest version (4.6.1) and install it in a new directory?
I ask because 1) a fresh install would not include the Column Expressions node, you have to get that from a separate extension and 2) in 4.6.1 the Advanced tab in the dialog should exist.
To get a zip file for KNIME AP (Windows), you can go here: KNIME Analytics Platform for Windows (zip archive) | KNIME
And to get the KNIME extensions as a zip file, refer to this specific bit of our documentation here: KNIME Analytics Platform Installation Guide
Hi Scott,
Yes I have download and installed version 4.6.1 with all extensions. Please see the attachments below but I still get the same error as attached.
Previously I use to have version 4.5.2 and by installing an update attached called ws.palladian.knime.update the java invoke error was gone, Is there a similar update for version 4.6.1?
Thanks,
Akash.
The 4.6 version of the Palldian extension is available as a ZIP file here if you want to try that: https://download.nodepit.com/palladian/4.6.zip
I’m not sure why it would resolve the issue with Column Expressions though
