I get the above error when trying to use any of the Functions in the String Manipulation node, e.g. toNull(str…)
Other nodes are working OK.
I am using Mac OS X 10.7.5 (Lion) with KNIME 3.5.3.
Previously the node was working, I think the change may have been caused by incrementally updating Knime. I guess probably a clean install might solve this, but just wondering if there is some quicker way to solve it.
I have a memory that a direct install of Knime 3.5 is not ‘possible’ on Lion, so I installed an earlier version (3.2) and then incrementally updated it (according to which nodes I actually needed) - perhaps that is why occasional errors like this are now beginning to appear? Any workarounds, to stay with Knime 3.5?
