Well, the problem is that you need to run it from an UI-thread. The code
below shows a helper to do it:

if cmd =3D=3D 'onCreateActions':
    from org.eclipse.jface.action import Action
    from org.python.pydev.core.docutils import PySelection
    from org.eclipse.ui.texteditor import IEditorStatusLine
    from org.eclipse.swt.widgets import Display
    from java.lang import Runnable

#------------------------------------------------ HELPER TO RUN THINGS IN
THE UI

    class RunInUi(Runnable):
        '''Helper class that implements a Runnable (just so that we
        can pass it to the Java side). It simply calls some callable.
        '''

        def __init__(self, c):
            self.callable =3D c
        def run(self):
            self.callable()

    def runInUi(callable):
        '''
        @param callable: the callable that will be run in the UI
        '''
        Display.getDefault().asyncExec(RunInUi(callable))

#------------------------------------------------ END HELPER TO RUN THINGS
IN THE UI

    class ExampleCommand3(Action):
        def run(self):
            def callable():
                statusLine =3D editor.getAdapter(IEditorStatusLine)
                if statusLine is not None:
                    statusLine.setMessage(True, "foo", None)
            runInUi(callable)

    editor.addOfflineActionListener("e", ExampleCommand3(), 'Example on how
to bind script action', False)
