Description

Consider a content like

+ /test
   - foo=bar

with index def faceting multiple properties - something like

+ /oak:index/foo/indexRules/nt:base/properties
   + foo
      - propertyIndex=true
      - facets = true
    + bar
      - facets = true

Then a query like

SELECT [rep:facet(foo)], [rep:facete(bar)] FROM [nt:base]

should not fail.

Note that the failure requires requesting on multiple facets and one of them must not have any indexed value.
