Eclipse Commands != GEF Commands? [message #212323]

I am currently writing my Diplomarbeit (like master thesis) and momentarily
got realy confused in my "Actions and Commands" chapter. After finishing my
description of Commands being abstract commands without any implementation
and Actions being th place where all the fun stuff goes, GEF Commands seem
to be the only Place to implement the ... oh action/command/what the heck!
.... the things that have to be done ;)

Do I simply have to keep in mind that Commands are something completely
different, even if they have the same names?

The typical workflow is that an action is the placeholder in the UI for the
invokation of a command. The action class sends a request to the target to
retrieve a concrete command. Then the command is executed on the command
stack.

The GEF commands aren't currently integrated with the IOperationHistory
framework available in Eclipse right now. This will be one of the potential
work items in > 3.2.

Hi Steven,

well this is the way it is done in GEF ... my point was, that in a normal
Eclipse Plugin or RCP application the command posesses no real
implementation but is nothing more than a placeholder.

A command is a different concept in UI. They chose this name in 3.0 knowing
that both GEF and EMF were using command to mean something else. Oh well.
