  This Letter reports observations of an event that connects all major classes
of solar eruptions: those that erupt fully into the heliosphere versus those
that fail and are confined to the Sun, and those that eject new flux into the
heliosphere, in the form of a flux rope, versus those that eject only new
plasma in the form of a jet. The event originated in a filament channel
overlying a circular polarity inversion line (PIL) and occurred on 2013-03-20
during the extended decay phase of the active region designated NOAA
12488/12501. The event was especially well-observed by multiple spacecraft and
exhibited the well-studied null-point topology. We analyze all aspects of the
eruption using SDO AIA and HMI, STEREO-A EUVI, and SOHO LASCO imagery. One
section of the filament undergoes a classic failed eruption with cool plasma
subsequently draining onto the section that did not erupt, but a complex
structured CME/jet is clearly observed by SOHO LASCO C2 shortly after the
failed filament eruption. We describe in detail the slow buildup to eruption,
the lack of an obvious trigger, and the immediate reappearance of the filament
after the event. The unique mixture of major eruption properties observed
during this event places severe constraints on the structure of the filament
channel field and, consequently, on the possible eruption mechanism.
