------------------------------------
> LDPath - ReversePropertySelector not working
> ---------------------------------------------
>
> Key: MARMOTTA-664
> URL: https://issues.apache.org/jira/browse/MARMOTTA-664
> Project: Marmotta
> Issue Type: Bug
> Reporter: Dietmar Glachs
> Assignee: Dietmar Glachs
> Priority: Minor
>
> The LDPath ReversePropertySelector is not working properly.
> the method receives the current node in the *context* parameter, but passes
> this node as the property to the subsequent call to
> _rdfBackend.listSubjects(context, property)_!
> {code}
> if(path != null && resultPaths != null) {
> Collection<Node> results = rdfBackend.listSubjects(context, property);
> for(Node n :results) {
> resultPaths.put(n, new
> ImmutableList.Builder<Node>().addAll(path).add(context).add(n).build());
> }
> return results;
> } else {
> return rdfBackend.listSubjects(property, context);
> }
> {code}
> The rdfBackend-interface however expects the property as the first argument.
> {code}
> Collection<Node> listSubjects(Node property, Node object);
> {code}
> The call to listSubjects with _changed_ attributes is only called when both
> *path* and *resultPaths* are _null_.
> when having a statement like the following
> {code}
> provider_name = ^cac:Item / ^cac:GoodsItem / rdfs:label ::xsd:string;
> {code}
> the path is initialized with the context node, and the resultPaths is an
> emply list - e.g. both not null. and the *wrong* line is executed ...
