I'm working on a SAPUI5 application and want to display a list of data records using a sap.ui.comp.smarttable.SmartTable.
Fiddling around with the Smart Table samples from the SAPUI5 Explored App I was able to get the Smart Table running against an OData service provided by a mock server.
Smart Table in XML view
<smartTable:SmartTable tableType="ResponsiveTable"
entitySet="RecordSet" enableAutoBinding="true" />
Corresponding lines of metadata.xml
<Schema Namespace="my.namespace" sap:schema-version="1" xmlns="http://schemas.microsoft.com/ado/2008/09/edm">
<ComplexType Name="ShortReference">
<Property Name="Type" Type="Edm.String" Nullable="false" sap:label="Reference type" />
<Property Name="Key" Type="Edm.String" Nullable="false" sap:label="Reference key" />
</ComplexType>
<EntityType Name="Record" sap:label="Record" sap:content-version="1">
<Key>
<PropertyRef Name="RecordID" />
</Key>
<Property Name="RecordID" Type="Edm.String" Nullable="false" sap:label="Record ID" sap:creatable="false" sap:updatable="false" />
<Property Name="ShortReference" Type="my.namespace.ShortReference" />
</EntityType>

<EntitySet Name="RecordSet" EntityType="my.namespace.Record" />
</EntityContainer>
<!-- Default columns shown by Smart Table -->
<Annotations Target="my.namespace.Record" xmlns="http://docs.oasis-open.org/odata/ns/edm">
<Annotation Term="com.sap.vocabularies.UI.v1.LineItem">
<Collection>
<Record Type="com.sap.vocabularies.UI.v1.DataField">
<PropertyValue Property="Value" Path="RecordID" />
</Record>
<!-- The following doesn't work - it won't be shown in a Smart Table column -->
<Record Type="com.sap.vocabularies.UI.v1.DataField">
<PropertyValue Property="Value" Path="ShortReference/Key" />
</Record>
<Record Type="com.sap.vocabularies.UI.v1.DataField">
<PropertyValue Property="Value" Path="ShortReference/Type" />
</Record>
</Collection>
</Annotation>
</Annotations>
</Schema>
As you can see a data record has a complex property of type my.namespace.ShortReference. I want the two properties to appear in the Smart Table as separate columns to be able to filter them.
I did have little success by using the <customData> aggregation as follows,
but as I'm having more than this single complex entity (including a complex entity with another complex entity) I'm searching for a simpler and more robust way to achive that goal. Furthermore, with <customData> my filtering ability in the p13n dialog is limited (no possibility to use filter like contains, starts with etc.).
Smart Table with custom data
<smartTable:SmartTable tableType="ResponsiveTable"
entitySet="RecordSet" enableAutoBinding="true" >
<Table>

"columnKey": "ReferenceType",
"leadingProperty": "ShortReference/Type",
"sortProperty": "ShortReference/Type",
"filterProperty": "ShortReference/Type",
"columnIndex": "9"
}' />
</customData>
<Label text="Reference type"/>
</Column>
<Column>
<customData>
<core:CustomData

</customData>
<Label text="Reference key"/>
</Column>
</columns>
<items>
<ColumnListItem>
<cells>
<Text text="{ShortReference/Type}" />
<Text text="{ShortReference/Key}" />
</cells>
</ColumnListItem>
</items>
</Table>
</smartTable:SmartTable>
So, is this even possible to achieve? Or do I have to flatten my OData entity?
I would also change to a normal sap.m.Table if it's easier. I have chosen the Smart Table because of it's sorting, filtering, grouping abilities and the variant management (I need all of those).
