I'm not able to reproduce this yet, so some additional detail will be
necessary. To make sure we're on the same page, try the query in the
Help files for tops:foreach. Open TopBraid/Examples/kennedys.rdf and
copy the following query into the SPARQL view:
SELECT *
WHERE {
?x tops:foreach (kennedys:Gender kennedys:College kennedys:Person
kennedys:Profession)
}
(BTW, tops:for each is rarely used - in most cases SPARQL's triple
match will do what is necessary - it already has a "for each" built
in. Ask if that doesn't make sense.)
If you are trying something else, please let us know. Are you trying
to build a Java plug-n extension?
