Dear Community please help
I am having serious issues using KNIME since i upgraded it to the newer version. I have rebooted my machine at least 3/4 times. I cannot use my old work. Today it has taken me 3-4 hours just to figure out how to rename columns, and I still have not been able to do so. I cannot open the configuration dialogue box when I double-click on the Column Renamer node. I tried using the Column Rename (Dictionary) node but had no luck there as well. I cannot double-click on many column-related nodes, and it looks like I am missing an extension. For example, I cannot double-click on the Column Filter node either.
Please help. this is too depressing and frustrating
I’m sorry to hear of your frustration and problems today, and that there has been some confusion here with the 5.5 release. You aren’t alone in having difficulty with working out how the configuration now works, and hopefully this will help ease the frustration
Please see this topic, regarding the change to the way the configuration now functions:
