Comment 1 Paul Webster CLA 2011-06-08 13:12:14 EDT 
There's a blind cast to an SWT ToolItem, but that can be a MenuItem (in this case) or even a random Control (in the keybinding case).

But I think this command wants to be a toggle command.

See org.eclipse.example.commands.monitorCount as an example of a toggle command that saves its state between runs.  https://github.com/paulweb515/commandsEclipseCon2011/blob/master/org.eclipse.example.commands/plugin.xml and https://github.com/paulweb515/commandsEclipseCon2011/blob/master/org.eclipse.example.commands/src/org/eclipse/example/commands/MonitorCountHandler.java
