I need to collapse a field when it's null or empty.
I have this jrxml source code

<textField>
 <reportElement x="180" y="0" width="200" height="20" uuid="5d7e1430-4275-4c04-a609-b12adf976cd2"/>
 <textElement markup="styled">
 <font isBold="true"/>
 </textElement>
 <textFieldExpression><![CDATA[$Ftitle]]></textFieldExpression>
 </textField>
 <textField isStretchWithOverflow="true" isBlankWhenNull="false">
 <reportElement positionType="Float" x="180" y="20" width="200" height="20" isRemoveLineWhenBlank="true" uuid="3e10e11d-131e-4059-b885-0210e651b5bd">
 <printWhenExpression><![CDATA[$Fvote != null && !$Fvote.equals("")]]></printWhenExpression>
 </reportElement>
 <textElement>
 <paragraph lineSpacing="Proportional"/>
 </textElement>
 <textFieldExpression><![CDATA["Voto: "+$Fvote]]></textFieldExpression>
 </textField>
 <textField>
 <reportElement x="180" y="40" width="200" height="30" uuid="2623f12e-a68f-4173-8f64-69a54ce50a0a"/>
 <textFieldExpression><![CDATA[$ForganisationName]]></textFieldExpression>
 </textField>

The Field Vote sometimes is empty or null and with $Fvote != null && !$Fvote.equals("")] it isn't displayed, but the space remain white and it doesn't disappear.

This is my result

This is what I want

Where am I wrong?
