    This method empties the SfxViewFrame, i.e. takes the <SfxObjectShell>

    SfxObjectShell (by which they may even destroy themselves).

    Thus, by invoking ReleaseObjectShell() and  SetObjectShell() the
    SfxObjectShell can be replaced.

    Between ReleaseObjectShell() and SetObjectShell() the control cannot
    be handed over to the system.
