[vtkusers] Animating vtk files

[PsyVis]

Hello 

I'm trying to animate through a series of PolyData .vtk files in java - The
first frame loads fine then when I press the start button to animate through
the files the whole app crashes.

Here is the method for changing the timeslice which is executed inside a
thread.

public void changeTimeSlice(int n) {

        frameCount = n;

        wlFile = new String(wlDir + File.separator + File.separator +
dataName + "_WATER_ELEVATION_" + frameCount + ".vtk");                                            
// file to be loaded     
       
        wl.getPartwl().SetFileName(wlFile);                  // set the
PolyData Readers filename
        wl.getPartwl().Modified();                              // tell the
PolyDataReader that it has been modified
        wl.getPartwl().Update();                               // force a
read on the polyDataReader
        
        wl.getPartMapperwl().Update();                     // tell the
PolyData Mapper to update
       
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
              
                rp.getRenWin().Modified();                      // tell the
renderpanel that it has been modified
                rp.getRenWin().Render();                        // tell the
render panel to render
            }
        });
    }

Here is the debug file for the PolyDataReader:

I've checked it is getting the right files, I am in a bit of bewilderment
over this.

Cheers
