Jacek Sputowski created OLINGO-897:
--------------------------------------
Summary: Cannot filter on derived properties - startTypeFilter in
MemberImpl is ignored
Key: OLINGO-897
URL: https://issues.apache.org/jira/browse/OLINGO-897
Project: Olingo
Issue Type: Bug
Components: odata4-server
Reporter: Jacek Sputowski
Priority: Blocker
According to [Addressing Derived
Types|http://docs.oasis-open.org/odata/odata/v4.0/cs01/part2-url-conventions/odata-v4.0-cs01-part2-url-conventions.html#_Toc365046429]
user should be able to filter on derived field
Example:
http://host/service/Customers?$filter=Model.VipCustomer/PercentageOfVipPromotionProductsOrdered
gt 80
Information about type (e.g. Model.VipCustomer) is stored in field
*startTypeFilter*(in MemberImpl), but it is not passed to ExpressionVisitor in
*accept* method. ExpressionVisitor get only path. startTypeFilter is ignored,
so it can't be used in *visitMember* method.
Suggested changes (please verify):
* in org.apache.olingo.server.api.uri.queryoption.expression.ExpressionVisitor
{code:java}
T visitMember(Member member) throws ExpressionVisitException,
ODataApplicationException;
//current version: T visitMember(UriInfoResource member) throws
ExpressionVisitException, ODataApplicationException;
{code}
* in org.apache.olingo.server.core.uri.queryoption.expression.MemberImpl
{code:java}
@Override
public <T> T accept(final ExpressionVisitor<T> visitor) throws
ExpressionVisitException, ODataApplicationException {
return visitor.visitMember(this);
//current version: return visitor.visitMember(path);
}
{code}
