Javascript Bar Chart not working after first execution anymore

I have two Javascript Bar Chart nodes, which work well in the first execution.
After this, in the next run both stop at 40% progress (Generating Image) and do not work any more.
I have to Stop KNIME and kill the remaining process in the task manager.

Then I restart KNIME and it is possible to run the workflow again, for one time.

This does not happen if a do not create the image, but I need the image in a report.

I use KNIME 4.5.1

What should I do?


Thank you for this post. We will deliver a fix in the upcoming version (4.5.2). Sorry for the inconvenience and thank you for your patience.
