             Summary: Cast type (typeFilterOnCollection) not taken into account while expanding a collection
                 Key: OLINGO-964
                 URL: https://issues.apache.org/jira/browse/OLINGO-964
             Project: Olingo
          Issue Type: Bug
          Components: odata4-server
    Affects Versions: (Java) V4 4.2.0
            Reporter: Jacek Miłaczewski
            Priority: Critical
         Attachments: 0001-fix-proposal-for-cast-type-not-taken-into-account-wh.patch

When user want to expand collection of entities (e.g. 'Products') with casting type of this collection to some subtype (''FeaturedProduct) and use property from this subtype as navigation property to be expanded ('Advertisement'), error occurs because of not taking into account this subtype in ExpandParser.java code but use only superType instead.

Example url:

http://.../OData.svc/Categories(1)?$expand=Products/ODataDemo.FeaturedProduct($expand=Advertisement)

I attach a patch with proposal fix to illustrate what is going on and how it should work in my opinion.
