<p>I have a simple text field in a subreport.</p>
<p><strong>Goal:</strong> Apply <em>"propertyExpression"</em> for <em>"Forecolor"</em> only when the parameter "evenRow" is <strong><em>1</em></strong></p>
<p>Following does not work but I gave it a try...</p>
<p> </p>
<pre language="xml"><textField>
<reportElement key="" mode="Transparent" x="108" y="1" width="76" height="13">
<propertyExpression name="net.sf.jasperreports.style.forecolor">
<![CDATA[$P{evenRow}.equals("1") ? $P{colorZebra1_text} : ""]]>
</propertyExpression>
</reportElement>
<textElement><font fontName="SansSerif" size="8"/></textElement>
<textFieldExpression>"Text"</textFieldExpression>
</textField>
</pre>

($V{REPORT_COUNT}.intValue() % 2 == 0 ? 1 : 0)</pre>
<br />
<p><strong>Question:</strong> How can I create a propertyExpression for the dynamic "Forecolor" that only comes to effect when my parameter <em>"evenRow"</em> is set to <strong><em>1</em></strong> ?</p>

<p><em>Note:</em> I am aware I could use <a href="http://community.jaspersoft.com/blog/change-font-color-based-condition-j..." rel="nofollow noreferrer">conditional styles</a> -> The problem with styles in general is that they are never dynamic, i.e. I would have to create 1 style for every single color that 'could' be set ...and because the color can be set to whatever hex value this is not an option.</p>
