VTK not mapping?

[doutriaux1]

In case of multiple mappers only the last one seems to be drawn, might be same issue as #855
data can be found at:

https://github.com/doutriaux1/VTKLearning/blob/master/uvcdat_bugs/charles.nc

Code:

import cdms2,vcs,os,sys,numpy
x=vcs.init()
b=x.createboxfill()
b.levels=numpy.arange(.5,15.5).tolist()
cols = vcs.getcolors(b.levels)
b.fillareacolors=cols
b.boxfill_type="custom"
pth= os.path.dirname(__file__)
f=cdms2.open(os.path.join(pth,"charles.nc"))
s=f("data2") 
x.plot(s,b)
x.png("lastmapper")
raw_input("Press enter")

w/o specification of levels we cansee there is data everywhere
