Here is the procedure to generate what I'm claiming is a problem:<br><br>1) Add a cone source<br>2) Use "Select Points Through" to select a point of the cone<br>3) Apply the ExtractSelection filter. The ExtractSelection1 object now has 1 Point and 1 Cell on the Information tab of the Object Inspector.<br>
4) File->Save State. Save the state as test.pvsm<br>5) close paraview<br>6) open paraview<br>7) load test.pvsm through File->Load State<br><br>The ExtractSelection1 object in the pipeline now has 0 cells and 0 points. Is this the expected behavior? If so, can someone explain it?<br>
<br clear="all">Thanks,<br><br>David<br>
