[Paraview] streamline tracer does not work on cut filter results

[Michael Ahlmann]

I had a similar problem when trying to visualize an axi-symmetric data 
set.  The problem was that the streamlines were not confined to the the 
axi-symmetric plane, and thus they were cut short at the point where the 
flow went in the circumferential direction.  The fix in my case was to 
use the calculator to develop a new, simplified data set.

V = V_x * ihat + V_y * jhat + 0 * khat

This way, the axi-symmetric component is zero, and doesn't affect the in 
plane streamlines.  I wonder if you could do something similar in your 
case?  Although I presume it would be more complex given that your 
cutting plane may not lay perfectly within one of the Cartesian planes...
