Hi Knime-Support-Team,
I possibly stumbled across a bug in a string manipulation (variable) node used within column list loop. The value of the first iteration is 0 which I suspect to cause the error …
Invalid settings: Unable to compile expression ERROR at line 60 The method join(java.lang.String...) in the type org.knime.base.node.preproc.stringmanipulation.manipulator.JoinManipulator is not applicable for the arguments (java.lang.Integer)
Edit #1: Same when I try to use a simple string manipulation node:
Edit #2: Also not possible when I convert the variable first to row
Kind regards
Mike
