Accessing a field from jr:table issue

 Hello, 

I'm trying to generate a report with a table which contains fields from a JRBeanArrayDataSource.

However, I'm pretty stuck, because the table simply isn't displayed in the report (although no error is reported).

This is what I want to obtain:

However, the report contains a simple horizontal line instead of the table. 

I'm trying to use the jr:table as follows: 

1) First, I'm using a JRBeanArrayDataSource constructed with the following array of objects: 

  public static Object[] createBeanCollection() {

        Object[] reportRows= new Object[2];

        reportRows[0] = new FilterData("east");  //public FilterData(String territory)

        reportRows[1] = new FilterData("wast");

        return reportRows;

    }

    where FilterData is a simple javabean, having a "territory" property.

1) In my jrxml, I declared a subdataset containing the territory field. 

<subDataset name="Table Dataset 1">

   <field name="territory" class="java.lang.String"/>

</subDataset>

( I am not sure if this approach is ok. Does declaring the field "territory" in the subDataset enable me to use $F{territory} in jr:detailCell? Because this is what I'm doing...and it doesn't work).

2) I'm trying to use this subDataset in a jr:table, as follows: (in the <detail> <band> section) 

<jr:table xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/componentshttp://jasperreports.sourceforge.net/xsd/components.xsd">

     <datasetRun subDataset="Table Dataset 1">

    <dataSourceExpression><![CDATA[$P{REPORT_DATA_SOURCE}]]></dataSourceExpression>

     </datasetRun>

     <jr:column width="90">

  <jr:columnHeader style="table_CH" height="30">

<staticText>

                 <reportElement x="0" y="0" width="90" height="30"/>

         <text><![CDATA[Territory]]></text>

</staticText>

           </jr:columnHeader>

  <jr:detailCell style="table_TD" height="20">

<textField>

         <reportElement x="0" y="0" width="90" height="20"/>

   <textFieldExpression class="java.lang.String"><![CDATA[$F{territory}]]></textFieldExpression>             

</textField>

  </jr:detailCell>

  </jr:column>

</jr:table>

Do you have any idea on what I' m doing wrong here? 

Thanks a lot! 

Teo
