I found a way to do this programmatically. The two functions above do
not work, so to fix it I have to do in this way:

# The composer window (you have to find the right composerView object
from iface.activeComposers() )
composer = composerView.composerWindow()

# Find the Command History Dock from ccomposer main Window
commandDock = composer.findChildren ( QDockWidget, "CommandDock" )[0]

# Find the QUndoView widget
undoView = commandDock.findChildren ( QUndoView )[0]

# Select the first element in command history (with text <empty>)
index = undoView.model().index (0, 0)
undoView.setCurrentIndex ( index )

# Select the second (but this may vary) element (the map object)
index = undoView.model().index (1, 0)
undoView.setCurrentIndex ( index )


TA-DAH! Now it shows the item properties of the MAP!!!!
