Incorrect casting exception #98
Description
Description
Trying to retrieve subtypes of meta types throws with an incorrect cast exception.
Environment
Client-java Master (1.7.2) tests
Reproducible Steps
Create this test somewhere in client-java
@Test
public void subtypes() {
GraknClient.Session session = client.session("subs");
GraknClient.Transaction tx = session.transaction().write();
tx.execute(Graql.parse(" define name sub attribute, value string;").asDefine());
tx.commit();
tx = session.transaction().write();
List<? extends SchemaConcept.Remote<?>> subs = tx.getSchemaConcept(Label.of("thing")).subs().collect(Collectors.toList());
System.out.println(subs);
}
Expected Output
Should return the subtypes of thing: thing and name
Actual Output
The concept [grakn.client.concept.type.impl.AttributeTypeImpl.Remote{tx=grakn.client.GraknClient$Transaction@3d1848cc, id=V4272}] is not of type [interface grakn.client.concept.type.MetaType$Remote]
