RequestData called twice in parallel
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
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.
To reproduce: First run a parallel server, attach a debugger and set a breakpoint in "vtkArrayCalculator::RequestData" Create a Box source Use calculator to add an array, e.g. "coordsX" Click Apply [ RequestData gets called twice ] Update arrat , e.g. "coordsX + 0" Click Apply [ RequestData only gets called once ]
