How to use Type comparison?

[Reza Hay]

Hi All,

The following Ruta (2.6.0) statement gives me correct answer:
TYPESYSTEM Types.DKPROTypeSystem;
IMPORT de.tudarmstadt.ukp.dkpro.core.api.syntax.type.dependency.ROOT FROM 
Types.DKPROTypeSystem AS DEP_ROOT;

DEP_ROOT{DEP_ROOT.Governor.pos.PosValue == "VBZ" -> LOG("root: " + 
DEP_ROOT.Governor.pos.ct)};

However, the following statement (comparing types) results in empty output:
DEP_ROOT{DEP_ROOT.Governor.pos == VERB -> LOG("root: " + 
DEP_ROOT.Governor.pos.ct)};

Isn't it possible to compare types as I did?

Regards,
Reza
