I observed a very nasty bug in the current KNIME version 4.1.2. When loading a workflow with any JFreeChart node in I get an error at loading: “Errors during load - Reason: testWF 3 loaded with errors” and all JFreeChart nodes are gone!
However, the bug is very simply to reproduce:
Create a new WF
Drag one JFreeChart node into the WF
Save the WF
Load the WF
… as a result, you see the error message and an empty WF!
The nasty thing is, that this bug is destroying every WF having some JFreeChart-nodes and using the JS nodes causes problems due to very strict security constraints (blocking build in Chrome).
Hello Erich,
I just tried it on my Laptop with macOS and could not observe the described behaviour. I am also using KNIME 4.1.2. Could you check something for me? When you open the workflow folder in your file system browser (Windows Explorer, Finder, Terminal, …) you find a directory for each node. In such a directory, there is a settings.xml file. Could you upload the settings.xml file for a JFreeChart node in such a broken workflow here? I am most interested in this part:
