[Paraview-developers] Slicing / Selection Widget in Paraview/Web

[Sebastien Jourdain]

The widget proxy is not properly python wrapped.

To solve the issue you need to do:

dataInfo = dataSet.GetDataInformation(0)
sliceWidgetW = simple.servermanager. _getPyProxy(sliceWidget)
sliceWidgetW.PlaceWidget = dataInfo.GetBounds()
