    You also need to configure eager fetching for the field where you are using valueXPath (see previous post).

    I've changed my datasource to
    Code:
    <DataSource ID="order_DataSource" serverType="jpa"
	serverContructor="com.isomorphic.jpa.JPA2DataSource" schemaBean="com.realanywhere.domain.OrderHeader"
	autoDeriveSchema="true">

	<fields>
		<field name="id" hidden="true" type="sequence" primaryKey="true" />
		<field name="version" hidden="true" />
		<field name="shipToName" valueXPath="shipTo/name" />
		<field name="shipFromName" valueXPath="shipFrom/name" />
		<!-- <field name="shipToName" includeFrom="shipTo_DataSource.name" /> -->
		<!-- <field name="shipTo" foreignKey="shipTo_DataSource.id" /> -->
		<!-- <field name="shipFromName" includeFrom="stakeholder_DataSource.name"/> -->
		<!-- <field name="shipFrom" foreignKey="stakeholder_DataSource.id" /> -->
		<field name="carrier" type="enum" title="Carrier">
			<valueMap>
				<value>FRANCOPARTENZA</value>
				<value>RAILWAY</value>
				<value>FRANCOARRIVO</value>
			</valueMap>
		</field>

		<field name="orderLines" multiple="true" TITLE="Order lines"
			type="orderLine_DataSource" javaClass="com.realanywhere.domain.OrderLine" />
	</fields>
</DataSource>
    but still no luck.

    Error log is:

    You don't have to declare "rest/json interface", just use valueXPath instead of includeFrom.

    Sorry I didn't really catch your suggestion about field.valueXPath

    Do you mean I have to define a rest/json interface?
    Can you point me to a sample/doc?

    Thank you.

    Looks like you are hoping that each of the includeFrom's will be associated with the preceding foreignKey. This isn't the case; currently there isn't a way to use multiple includeFroms from the same related DataSource.

    There are many ways around this, but one is to configure eager fetching for one of the two entities (say shipFrom) and use field.valueXPath.

    started a topic multiple includeFrom

    multiple includeFrom

    Hello,
    I receive an error while including two fields from the same datasource.


    WARN DataSource - Couldn't get value at valueXPath: shipFrom/name for datasource: order_DataSource - ignoring. Actual error: org.apache.commons.jxpath.JXPathNotFoundException: No value for xpath: shipFrom/name

    The value for both the included fields is not shown.

    Datasource is:

    Code:
    <DataSource ID="order_DataSource" serverType="jpa"
	serverContructor="com.isomorphic.jpa.JPA2DataSource" schemaBean="com.realanywhere.domain.OrderHeader"
	autoDeriveSchema="true">

	<fields>
		<field name="id" hidden="true" type="sequence" primaryKey="true" />
		<field name="shipToName" includeFrom="stakeholder_DataSource.name"/>		
		<field name="shipTo" foreignKey="stakeholder_DataSource.id" />
 		<field name="shipFromName" includeFrom="stakeholder_DataSource.name"/>
 		<field name="shipFrom" foreignKey="stakeholder_DataSource.id" />
        ...
        </fields>
</Datasource>
    while the classese are JPA mapped pojos like:
    Code:
    public class OrderHeader {	

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;

    String orderNumber;
	
    @ManyToOne(fetch = FetchType.LAZY)
    Stakeholder shipTo;
	
    @ManyToOne(fetch = FetchType.LAZY)
    Stakeholder shipFrom;
        ...
    Code:
    public class Stakeholder {	

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long id;

    String name;

    ...
}
    BTW: if i comment out the "shipFrom" definition (NULL in the database) in OrderHeader datasource the remaining field shipTo is correctly shown.

    How should the datasource be defined?

    THank you!
