> 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
