an error of Widget's views

Hello

When using Widget node in KNIME Analytics Platform, the following error occurred.

I’d appreciate it if someone could tell me what is the reason of this error.

Thanks,

Hey hhkim,

can you provide a bit more information about your setup and what you are actually trying to achieve?
Can you share the workflow? That would probably be the easiest to see whats going on.

I just tried to test some node.
So there are no specific settings.
I think it was occurred by Refresh button Widget node.

In that case it is very hard to tell you what caused the error.
If you can provide an example workflow or some steps to reproduce I am happy to look into it.

Greetings,
Daniel
