> Invalid results of SPARQL query with a federated subquery

> Key: JENA-2280
> URL: https://issues.apache.org/jira/browse/JENA-2280
> Project: Apache Jena
> Issue Type: Bug
> Components: Fuseki
> Affects Versions: Jena 4.3.1, Jena 4.3.2, Jena 4.4.0
> Reporter: Michal Pietrusinski
> Assignee: Andy Seaborne
> Priority: Major
> Fix For: Jena 4.5.0
>
>
> In Fuseki I created on dataset named "test".
> The following query gives 1 result with an empty string, whereas the expected
> value is "test"
> {code:java}
> SELECT ?temp
> WHERE {
> {
> SELECT (?value as ?temp) {
> { SERVICE <http://localhost:3030/test/query> {
> VALUES ?value { "test" }
> }
> }
> }
> }
> }
> {code}
> However the following query returns the correct result "test".
> {code:java}
> SELECT *
> WHERE {
> {
> SELECT (?value as ?temp) {
> { SERVICE <http://localhost:3030/test/query> {
> VALUES ?value { "test" }
> }
> }
> }
> }
> }
> {code}
> Both of these queries work fine on an older Fuseki release 4.1.0
