Sometimes (its not reproducable) we encounter a NullPointerException in the SelectionLayer. I will add the Stacktrace. Don't really understand what Nattable tries to do here. We use Nattable 1.5

In that place it tries to render the selection border. There was a fix in the current development stage some months ago. So probably this is fixed already.

Will there be a Nattable 1.6 this year? Or can you point us at the fix, so that we can patch the Nattable ourselves?

I am working hard as much as I can on finishing 1.6. But as I am currently the only person that is active in this project, this is quite a big challenge.
You can check the history of the SelectionLayerPainter to see if you can point the fix.
