Issue
Fixes #4416.
When removing
Variable.make
, I assumed that we no longer neededLookup
inremove_unused_values
because values are mapped anyway. This doesn't work when the variable that is being purged hascompute_value
defined, for instance if the variable is a discretized version of some numeric variable.Description of changes
Re-add lookup.
Although the bug was in remover, I also kept the test in
test_owselectrows
, where we detected the problem.Includes
