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

             Summary: Filter condition on an expanded attribute fails with 
ClassCastException
                 Key: OLINGO-930
                 URL: https://issues.apache.org/jira/browse/OLINGO-930
             Project: Olingo
          Issue Type: Bug
    Affects Versions: V2 2.0.6, V2 2.0.5
            Reporter: Darren Lindley


i installed the sample cars/manufacturers application and tried this query:
http://localhost:8080/MyFormula.svc/Cars?$filter=ManufacturerDetails/Name%20eq%20%27SuperCar%27&$expand=ManufacturerDetails

this fails with the message:
class java.lang.ClassCastException : 
org.apache.olingo.odata2.core.edm.provider.EdmNavigationPropertyImplProv cannot 
be cast to org.apache.olingo.odata2.api.edm.EdmProperty

This appears to come from ODataExpressionParser:
{code:title=ODataExpressionParser.java|borderStyle=solid}
  private static String getPropertyName(final CommonExpression whereExpression) 
throws EdmException {
    EdmProperty property = ((EdmProperty) ((PropertyExpression) 
whereExpression).getEdmProperty());
    EdmMapping mapping = property.getMapping();
    String name = mapping != null ? mapping.getInternalName() : 
property.getName();
    return name;
  }
{code}
