[JBoss JIRA] (ISPN-8564) Cannot select inner entities in Ickle

Adrian Nistor commented on ISPN-8564:
-------------------------------------

The first query "SELECT p.child FROM Parent p" is wrong, so it's natural
that it fails with "org.infinispan.objectfilter.ParsingException: ISPN028503:
Property child can not be selected from type Parent since it is an embedded entity."

The second query, "SELECT p.child.name FROM Parent p" ,  is correct and it
works. A second variation of it ""SELECT child.name FROM Parent" does not
work. So I think the bug was closed by mistake. The PR I made was only supposed to add a
test for it.

 Cannot select inner entities in Ickle
 -------------------------------------

                 Key: ISPN-8564
                 URL: https://issues.jboss.org/browse/ISPN-8564
             Project: Infinispan
          Issue Type: Bug
          Components: Embedded Querying, Remote Querying
    Affects Versions: 9.0.0.Final
            Reporter: Gustavo Fernandes
            Assignee: Adrian Nistor
            Priority: Major
             Fix For: 9.4.0.Final

 Consider a proto mapping:
 {code}
 message Parent {
    optional Child child;
 }
 message Child {
    optional string name = 1;
 }
 {code}
 It is not possible to select any of the Child attributes in the query. The following
queries fail:
 {{SELECT p.child FROM Parent p}}
 Fails with ISPN028503
 {{SELECT p.child.name FROM Parent p}}
 Fails with ISPN028502: Unknown alias 'child'
