Description - When a variable has nested classifications (i.e. classifications that are more than 1 level deep), Classification Rule Builder is unable to operate on those nested classifications.
Why is this feature important to you - It is common to have classifications that are nested. Furthermore, the Rule Builder's interface implies that it can operate on nested classifications, when in reality, it cannot. This is the biggest bug.
How would you like the feature to work - When there is a rule that operates on a nested classification, then that rule should work in the same way as with top-level classifications.
Current Behaviour - Nested classifications cannot be classified with the Rule Builder, even though the Rule Builder interface implies that it can be done.
