When I add a hop between two steps, it always goes wrong.

一个未预期的错误发生在Spoon: probable cause:在停止Spoon前，请先关闭其它spoon窗口!

null

  • can you raise a Pentaho - JIRA ticket reg. this issue.? I assume it might be an issue with your installation or either windows10 is not compatible with the pentaho release. Not sure though. – Rishu Shrivastava Aug 19 '15 at 18:08
  • Pentaho Spoon works on my Windows 10 desktop with JDK 1.7, So this might not be a Windows issue. Can you please post your JDK version and what kind of repository are you using? – Devi Prasad Aug 28 '15 at 08:06
