             Summary: EntityType with Basetype, doesn't inherit a Function of 
the BaseType.
                 Key: OLINGO-972
                 URL: https://issues.apache.org/jira/browse/OLINGO-972
             Project: Olingo
          Issue Type: Bug
    Affects Versions: (Java) V4 4.2.0
            Reporter: Melissa Ibeth Vargas Lobo


This is my BaseEntity:

<EntityType Name="BaseEntity" Abstract="true">
<Key>
<PropertyRef Name="ID"/>
</Key>
<Property Name="ID" Type="Edm.Int64"/>
</EntityType>

This entity has the next Function:

<Function Name="GetInvoices" IsBound="true" IsComposable="true">
<Parameter Name="entity" Type="ns.BaseEntity" Nullable="false"/>
<Parameter Name="param" Type="Edm.String" Nullable="false"/>
<ReturnType Type="Collection(Edm.String)"/>
</Function>

Now, I have an Entity which has a Basetype:

<EntityType Name="Hotel" BaseType="ns.BaseEntity">
<Property Name="Name" Type="Edm.String"/>
<Property Name="Description" Type="Edm.String"/>
<Property Name="Picture" Type="Edm.String"/>
<Property Name="Location" Type="Edm.String"/>
<Property Name="AvailableStartDate" Type="Edm.DateTimeOffset"/>
<Property Name="AvailableEndDate" Type="Edm.DateTimeOffset"/>
<Property Name="City" Type="ns.City"/>
<NavigationProperty Name="ReviewBooking" Type="ns.ReviewBooking" 
Nullable="false"/>
</EntityType>

<EntitySet Name="MyHotels" EntityType="ns.Hotel">
<NavigationPropertyBinding Path="ReviewBooking" Target="ReviewBooking"/>
</EntitySet>

So, when I try to use the Function GetInvoices:

http://localhost:8080/ODataService/MyHotels(103)/ns.GetInvoices(param='Name')

The response is:

<error xmlns="http://docs.oasis-open.org/odata/ns/metadata";>
<code>null</code>
<message>The part 'ns.GetInvoices' is not defined.</message>
</error>

I don't know if it's possible, if the Basetype Entity 'B' has a Function 'F', 
another Entity 'A' that has as BaseType 'B' can use the function 'F'.

Thanks.
