[Paraview] programmable sourece->programmable filter -> streamtracer parallel

[Atanas Atanasov]

Hi i have created the following pipeline on c++ based servermanager 
plugin(without qt)
->programmable source(creates a structured grid)->programmable 
filter(adds velocities and pressure on the vertices)
->ArbitrarySourceStreamTracer(Seeding thorugh points or thorugh 
line).This setup works fine with one process. In parallel
the streamlines are not shown. Do you have experience with such kind of 
problem?
