@Kazimierz please open a ticket with the KNIME support team regarding this behavior and include an example workflow and excel file that exhibits the issue so we can investigate.
@ArjenEX Please find description of the workaround. I’m not able to share that workflow as probably it refers to data shared privately as the file size exceeds limit for the forum.
Thanks for reporting! The internal ticket is AP-23371. Should not be long for the fix to hit the nightly and then the upcoming releases (5.3.3 and the next feature release).
Btw, you don’t have to use the Java Snippet node with a single row table. You can also use a Java Edit Variable, which has an optional input. Then, you can just put the number into the Java code.
