[Paraview] Programmable Source & MultiBlockDataSet

[Jérôme Plumecoq]

Hello,

I also would like to make a ProgrammableSource with a 
vtkMultiBlockDataSet as output type (*). It seems that the correction 
indicated below doesn't appear in the version 3.8.0 of ParaView.

do you know in which version this change will be integrate ?

does a patch exist ?

thanks.

Jérôme

(*) in fact, if I put the OutputDataSetType to 13, it takes 0 (the value 
default : vtkPolyData), but it seems to work...
