Error applying custom tooltips to a bar chart

I have this code:
chart.addAxis("y", {
  vertical: true,
  minorTicks: false,
  labels: [{text:'a',value: 1},{text:'b',value: 2},{text:'c',value: 3},{text:'d',value: 4},{text:'e',value: 5}]
});
chart.addAxis("x", {
  min: 0,
  max: 2,
  minorTicks: false
});
chart.addSeries('z', [2,1,2,0,1]);
It works perfectly. If I now try to add a custom tootip here modifying the series data
chart.addSeries('z', [{x:2, tooltip:'a'},{x:1, tooltip:'a'},{x:2, tooltip:'a'}..]);
It fails with a JS error. The error disappears when the values of x are all different (say 1,2,3,4,5) but even then no bar is painted. Can anyone spot the problem?

Regards
