Channels opeartions

Is it possible to work with the channels data (copy, paste selection) within the channels dialog without decomposition->composing an image into RGB channels.
I need to copy selection of a pupil from the green channel and paste it into the red channel to remove the red eyes. It works fine with image decomposition, but doesn't work by simply selection of appropriate channel in the channels dialog and deselection of other channels. Am I doing something wrong or it is "as designed"?

By the way, Windows GIMP compilations do not show selection edge with a line if another selection region has been added. The selection appears visible after focus change or something else. It has happened since 2.2.0.
