"Table Difference Checker" Node hangs when changing the difference checker


I currently encounter some weird problems with the Table Difference Checker Node on Mac OS X (system details see below). 

Given a clean workflow with only two Table Reader nodes and a Table Difference Checker, KNIME hangs when clicking "Ok" or "Apply" after setting the Checker to "Number with epsilon". I see no significant CPU usage for KNIME (or any other process) but the GUI becomes unresponsive and I have to kill KNIME via "Force Quit".

Sporadically it works if I only change the first column or (when changing only a single checker) change the epsilon before clicking "Apply".



System details:

  • Mac OS X 10.9.4
  • KNIME 2.10.1 (freshly downloaded)
  • Installed plugins: KNIME Testing Framework

Thank you for the report, I was able to reproduce the problem and have opened a bug report.
