How to create different page footer depending on a condition? - jasper-reports

Question

I have a requirement to show different footer depending on a condition.
My footer consists of many static labels and theoretically I can define a 'Print When Expression' for each of the labels. But it is inconvenient.
Q: Is it possible to select a different footer depending on a condition?
If not how else can I handle such situation without having to specify the condition in many places?

Answer 1

The xsd allows none or maximum one pageFooter tag with a maximum of one band.
but
This is a typical example where you can use the frame component, to group your data and decide if to display it.
Example displaying different frame with text fields depending on page number
<pageFooter>
<band height="60" splitType="Stretch">
<frame>
<reportElement x="0" y="0" width="540" height="60" uuid="d0198e94-8325-4909-9804-a8d393600ec5">
<printWhenExpression><![CDATA[$V{PAGE_NUMBER}%2!=0]]></printWhenExpression>
</reportElement>
<textField>
<reportElement x="0" y="0" width="100" height="30" uuid="379e2ac0-63ea-4493-bd38-1b7ca7b35d8c"/>
<textFieldExpression><![CDATA["Text Field 1"]]></textFieldExpression>
</textField>
<textField>
<reportElement x="0" y="30" width="100" height="30" uuid="6598ba79-08b6-4997-953d-70b64f159e3b"/>
<textFieldExpression><![CDATA["Text Field 2"]]></textFieldExpression>
</textField>
</frame>
<frame>
<reportElement x="0" y="0" width="540" height="60" uuid="d0198e94-8325-4909-9804-a8d393600ec5">
<printWhenExpression><![CDATA[$V{PAGE_NUMBER}%2==0]]></printWhenExpression>
</reportElement>
<textField>
<reportElement x="0" y="0" width="100" height="30" uuid="379e2ac0-63ea-4493-bd38-1b7ca7b35d8c"/>
<textFieldExpression><![CDATA["Text Field 3"]]></textFieldExpression>
</textField>
<textField>
<reportElement x="0" y="30" width="100" height="30" uuid="6598ba79-08b6-4997-953d-70b64f159e3b"/>
<textFieldExpression><![CDATA["Text Field 4"]]></textFieldExpression>
</textField>
</frame>
</band>
</pageFooter>
add the different text of the different pageFooter's to different frame's, then set printWhenExpression on the frame component.
