IEvaluationService variableFilter is loaded with several, but not all, ISources values...

{ ISources.ACTIVE_WORKBENCH_WINDOW_NAME,
ISources.ACTIVE_WORKBENCH_WINDOW_SHELL_NAME, ISources.ACTIVE_EDITOR_ID_NAME,
ISources.ACTIVE_EDITOR_INPUT_NAME,
ISources.SHOW_IN_INPUT,
ISources.SHOW_IN_SELECTION,
ISources.ACTIVE_PART_NAME,
ISources.ACTIVE_PART_ID_NAME,
ISources.ACTIVE_SITE_NAME,
ISources.ACTIVE_CONTEXT_NAME,
ISources.ACTIVE_CURRENT_SELECTION_NAME }

Why is ISources.ACTIVE_EDITOR_NAME omitted?

is this an intentional omission?

it seems that it belongs among them considering the inclusion of other ACTIVE_EDITOR values.

Thank you for your response, but it does not answer the question.

As you know ISources are the values behind core expression variables... https://wiki.eclipse.org/Command_Core_Expressions#Variables_and_the_Command_Framework

... and ISources.ACTIVE_EDITOR_NAME corresponds to activeEditor.

variableFilter prevents values in the Set from being added or removed from the workbench IEclipseContext in EvaluationService.changeVariable method.

My question is why is ACTIVE_EDITOR_NAME omitted from the Set?

WorkbenchSourceProvider sets all of the variableFilter ISources values. Only ISources.ACTIVE_EDITOR_NAME is allowed through the filter. This seems like an error of omission. Or is there some rationale for omitting it?
