Text: DATASET type invalid.
When I used Paraview4.2 or Paraview4.1 to export vtk file, I got this error: dataset type invalid.
If I use a higher Paraview version, it shows: dataset version invalid.
The flow I did: Open paraview, and open an example in paraview, save data as legacy vtk, select binary.
After this flow, I change the file in xml file, but the error occurs (dataset type invalid).
So, It is the problem of Paraview? Do I need to do some operations on vtk file before read it?
