Cannot resize `xindex` when appending array if `xindex` getter has been called
Created by: stefco
For some reason, calling the Series.xindex or, equivalently for timeseries, the TimeSeries.times getters causes problems when trying to append an array to another. I will look into this and try to fix it. If the getter is not called, appending works fine:
In [159]: t = TimeSeries.read('foo.hdf5')
...: # start = t.times[-1] + t.dt
...: # del start
...: start = 1175011260.0
...: # end = t.times[-1] + t.dt + Quantity(100, "s")
...: # del end
...: end = 1175011360.0
...: t2 = c.placeholder(t, start, end).copy()
...: t3 = t.append(t2)
In [160]: t = TimeSeries.read('foo.hdf5')
...: # start = t.times[-1] + t.dt
...: # del start
...: t.times
...: start = 1175011260.0
...: # end = t.times[-1] + t.dt + Quantity(100, "s")
...: # del end
...: end = 1175011360.0
...: t2 = c.placeholder(t, start, end).copy()
...: t3 = t.append(t2)
