<div>Hi,</div><div><br></div><div>Filters have their RequestData called twice when using a parallel server. This happens when the filter is first added - subsequent "Apply"s only called it once.</div><div><br></div>
<div>To reproduce:</div><div>First run a parallel server, attach a debugger and set a breakpoint in "vtkArrayCalculator::RequestData"</div><div>Create a Box source</div><div>Use calculator to add an array, e.g. "coordsX"</div>
<div>Click Apply [ RequestData gets called twice ]</div><div>Update arrat , e.g. "coordsX + 0"</div><div>Click Apply [ RequestData only gets called once ]</div><div><br></div><div>I've added a bug report - <a href="http://www.paraview.org/Bug/view.php?id=12546">http://www.paraview.org/Bug/view.php?id=12546</a></div>
