Constant expression results in Symbian tap plugin

All the axis comparisons in \qtmobility\plugins\sensors\symbian\tapsensorsym.cpp switch-case structure's default branch are always true regardless of the values of its operands:

default:
{
// Indicates a tap on X axis
if(iData.iDirection==KSensrvAccelerometerDirectionXplus|KSensrvAccelerometerDirectionXminus)

{ iReading.setTapDirection(QTapReading::X); }

// Indicates a tap on Y axis
else if(iData.iDirection==KSensrvAccelerometerDirectionYplus|KSensrvAccelerometerDirectionYminus)

{ iReading.setTapDirection(QTapReading::Y); }

// Indicates a tap on Z axis
else if(iData.iDirection==KSensrvAccelerometerDirectionZplus|KSensrvAccelerometerDirectionZminus)

{ iReading.setTapDirection(QTapReading::Z); }

// Undefined value
else

{ iReading.setTapDirection(QTapReading::Undefined); }

}
}
