[yt-dev] Problem with serialization and projections

[Michael Kuhlen]

Hi

I think I've found a bug with serialization and projections with a data_source.

If I do a projection providing a data_source everything is fine:

disk = pf.h.disk((0.5,0.5,0.5), (0,0,1), (10.0,'kpc'), (2.0,'kpc'))
pc = PlotCollection(pf)
pc.add_projection("NumberDensity","z",weight_field="Density", data_source=disk)


But then, if I do the exact same projection without a data_source, it
breaks with an error: 'No field named px'. The full traceback is at
http://paste.yt-project.org/show/2637/.

Note that if I first delete the .yt file, then the projection without
data_source works just fine.


Mike
