[protege-discussion] exception with SWRL->OWL using boolean datatype properties

I have two ontologies that I am importing into a new project.
Ontology_1 has individuals that I want to transfer to Ontology_2.  I
have written rules in SWRL that state that if there is an individual in
Ontology_1, Class_A , Property_A (datatype = Boolean), it will be placed
in Ontology_2, Class_B, Property_B, (datatype= boolean).  But I am
getting this error.  


Exception exporting knowledge to OWL:
xception: cannot convert value of type 'java.lang.Boolean' to String


How do I work around this?
