---------------------------------------

             Summary: LDPath - ReversePropertySelector with wrong code
                 Key: MARMOTTA-670
                 URL: https://issues.apache.org/jira/browse/MARMOTTA-670
             Project: Marmotta
          Issue Type: Wish
          Components: LDPath
    Affects Versions: 3.4.0
            Reporter: Dietmar Glachs
            Assignee: Dietmar Glachs
            Priority: Trivial
             Fix For: 3.4.0


The ReversePropertySelector is not retrieving the requested subjects properly when, and only when the parameters "path" and "resultPahts" are provided. 

Code snippet as currently implemented in ReversePropertySelector:

{code:title=ReversePropertySelector.java - select|borderStyle=solid}
...
if(path != null && resultPaths != null) {
  Collection<Node> results = rdfBackend.listSubjects(context, property);
  ...
  return results;
} else {
    return rdfBackend.listSubjects(property, context);
}
...
{code}

The *wrong* {{if}} part of the method is only used in marmotta-search (previously lmf-search) when parsing LDPath search programs, the {{else}} functionality is frequently used when parsing LDPath queries. 
however, the calls to listSubjects should be equal in {{if}} and {{else}}.
