Hi,
I am trying to use the perl scripting node in Knime 2.5.2 to process some text. However, I am having some trouble returning an array of strings. The simplest example I can find is the following:
@array = ("foo","bar");
return @array;
I get the following error message:
ERROR Perl Scripting Execute failed: Runtime class of object "2" (index 0) in row "Row1" is StringCell and does not comply with its supposed superclass ListCell (Collection of: StringCell)
I have seen that in a previous release note that a bug related to array return in the perl node was solved so maybe I am doing a really silly mistake but I can't find the way to solve it. Could someone help me?
Thanks in advance,
Luis
