Calculator Filter Malfunctions for Dataset Names starting with a Number
The Calculator filter malfunctions with dataset names that begin with a number.
For example, entering a calculation that should return a Result based on a dataset named
test_1 behaves correctly but a dataset named
1_test throws an error (see below). This behavior has been confirmed with legacy VTK (see attached) and HDF5-based XDMF files. The presence/absence of the underscore in the name has no effect.
Other filters appear to operate correctly with either dataset (e.g., Threshold).
Steps to reproduce on macOS 10.14.6:
- Launch ParaView 5.8.0
- File -> Open ->
- Filters -> Calculator
- Enter calculation formula
- Apply (works)
- Change calculation formula to
- Apply (fails)
