Hi,
I try to show some data (OData v4) in a table (sap.m.Table) and currently I'm facing an issue accessing content provided in a collection within response structure. The service has a definition like:
<EntityType Name="SalesRequest">
<Key>
<PropertyRef Name="SalesRequestId" />
</Key>
<Property Name="SalesRequestId" Type="Edm.Int32" Nullable="false" />
<Property Name="Status" Type="Edm.Int32" Nullable="false" />
<Property Name="Positions" Type="Collection(RequestPosition)" />
</EntityType>
<ComplexType Name="RequestPosition">
<Property Name="Position" Type="Edm.Int32" Nullable="false" />
<Property Name="Material" Type="Edm.String" />
<Property Name="Quantity" Type="Edm.Decimal" Nullable="false" />
</ComplexType>
How to bind a table cell to the first element returned in the Positions collection? The table should show something like:
/Postitions[0]/Material
What is the best approach to deal with embedded collections? I was not able to find a proper solution for this scenario:
* I tried to use a formatter, but binding a non-primitive type (the collection) is not possible
* I tried to use a sap.m.List as cell component, but the collection is not a valid list items aggregation
* ...
Any suggestions, links etc.? The OData service is provided by a third party (non-SAP) component.
Thanks.
Regards
Karsten
