Error after Knime crashed "No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab"

mwiegand · March 24, 2025, 5:48am

Good morning,

Knime crashed yesterday and upon opening it again, where a component was the first tab to appear, the error No editor descriptor for id org.eclipse.ui.internal.emptyEditorTab was thrown:

It has no direct implication. Hence just FYI.

Hi @mwiegand ,
Thanks for reporting this.

Thanks,
Sanket

Hi @mwiegand,

I assume you cannot reproduce the crash? Where did that happen, in the modern / web UI or in classic UI? Further, I assume you were starting straight into classic UI?

Best,
Ben

Hi @BenjaminMoser,

I did not darte to crash Knime recently as I have fallen behind my plans (for several reasons) and yes, I am predominantly using CUI.

If you ought to provoke / attempt to reproduce it, I’d:

Open a Component
Trigger a memory exhaustion
Manually kill the process
Restart

Sorry if I cannot be of more help on this. I got to get cracking

Best
Mike
