  1. POHow to use dynamic variable in "print when expression"?
    text
    copied!<p>I am using <em>iReport</em> for making PDF Report.<br/> My objectives are I want to use dynamic variable (name of variable is <strong><em>pgnum</em></strong>) in my 3 objects elements, and use <strong><em>pgnum</em></strong> in "print when expression" object properties.<br/> I have three objects elements, they are a text field, frame name’s frameA and frame name’s frameB.</p> <p>I want to make something like this in the print when expression :</p> <ul> <li>text field = print when expression : <strong>$V{pgnum} % 6 == 1</strong> </li> <li>frameA = print when expression : <strong>$V{pgnum} % 6 == 1</strong> </li> <li>frameB = print when expression : <strong>$V{pgnum} % 6 != 1</strong></li> </ul> <p>If I have total 14 pages in my PDF so the result I want are :</p> <ul> <li>When the page 7 and page 13, text field and frameA will be print.</li> <li>And the other page(except page 7 and page 13) only frameB will be print.</li> </ul> <p>I was tried all the way in <em>iReport</em> but the <strong><em>pgnum</em></strong> always be static result, even in text field the evaluating time properties is for every page. And frame A never be print too, because I think the <strong><em>pgnum</em></strong> is always set to be zero (0) value, and never be increment. So the result is frame B always be printed in all page. </p> <p>Can you help me to solve this problem using <em>iReport</em>? Or can you suggest or even help me using the other jasper report something like dynamic report or dynamic jasper to solve this problem ?</p> <p>NB:</p> <ul> <li>Name of the dynamic variable is pgnum.</li> <li>My pgnum has initial value 0 (zero)</li> <li>And has properties like this => class="java.lang.Integer" incrementType="Page" calculation="Sum"</li> </ul> <p>Thanks for reading. I’m waiting for your reply soon.</p> <p>Here is my <em>jrxml</em> file:</p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="deploy_details" language="groovy" pageWidth="502" pageHeight="842" columnWidth="502" leftMargin="0" rightMargin="0" topMargin="0" bottomMargin="0"&gt; &lt;style name="table_CH" mode="Opaque" backcolor="#999999"&gt; &lt;box&gt; &lt;pen lineWidth="0.5" lineColor="#000000"/&gt; &lt;/box&gt; &lt;/style&gt; &lt;variable name="pgnum" class="java.lang.Integer" incrementType="Page" calculation="Count"&gt; &lt;variableExpression&gt;&lt;![CDATA[pgnum+1]]&gt;&lt;/variableExpression&gt; &lt;initialValueExpression&gt;&lt;![CDATA[0]]&gt;&lt;/initialValueExpression&gt; &lt;/variable&gt; &lt;detail&gt; &lt;band height="762" splitType="Stretch"&gt; &lt;frame&gt; &lt;reportElement isPrintRepeatedValues="false" mode="Opaque" x="56" y="66" width="114" height="43" isRemoveLineWhenBlank="true" isPrintWhenDetailOverflows="true" backcolor="#000000"&gt; &lt;printWhenExpression&gt;&lt;![CDATA[$V{pgnum} % 6 == 1]]&gt;&lt;/printWhenExpression&gt; &lt;/reportElement&gt; &lt;staticText&gt; &lt;reportElement mode="Transparent" x="15" y="12" width="83" height="18" forecolor="#FFFFFF"/&gt; &lt;textElement/&gt; &lt;text&gt;&lt;![CDATA[FrameA]]&gt;&lt;/text&gt; &lt;/staticText&gt; &lt;/frame&gt; &lt;frame&gt; &lt;reportElement isPrintRepeatedValues="false" mode="Opaque" x="185" y="66" width="114" height="43" isRemoveLineWhenBlank="true" isPrintWhenDetailOverflows="true" backcolor="#000000"&gt; &lt;printWhenExpression&gt;&lt;![CDATA[$V{pgnum} % 6 != 1]]&gt;&lt;/printWhenExpression&gt; &lt;/reportElement&gt; &lt;staticText&gt; &lt;reportElement mode="Transparent" x="15" y="12" width="83" height="18" forecolor="#FFFFFF"/&gt; &lt;textElement/&gt; &lt;text&gt;&lt;![CDATA[FrameB]]&gt;&lt;/text&gt; &lt;/staticText&gt; &lt;/frame&gt; &lt;textField isStretchWithOverflow="true" evaluationTime="Page" isBlankWhenNull="true"&gt; &lt;reportElement isPrintRepeatedValues="false" x="122" y="35" width="100" height="20" isRemoveLineWhenBlank="true" isPrintWhenDetailOverflows="true"&gt; &lt;printWhenExpression&gt;&lt;![CDATA[$V{pgnum} % 6 == 1]]&gt;&lt;/printWhenExpression&gt; &lt;/reportElement&gt; &lt;box&gt; &lt;topPen lineWidth="3.25"/&gt; &lt;leftPen lineWidth="3.25"/&gt; &lt;bottomPen lineWidth="3.25"/&gt; &lt;rightPen lineWidth="3.25"/&gt; &lt;/box&gt; &lt;textElement/&gt; &lt;textFieldExpression&gt;&lt;![CDATA["textField"]]&gt;&lt;/textFieldExpression&gt; &lt;/textField&gt; &lt;/band&gt; &lt;/detail&gt; &lt;/jasperReport&gt; </code></pre> <p>Thanks Alex K for reply, but your answer still not solve my problem, I have tried and follow all of your order to solve this problem, but I still get the pgnum in static value (not increment). </p> <p>You suggested me before about dataSource, and now I have included the problem with new jrxml and dataSource example files in testing package. But I have a new problem, the result (dummyData) which I created is always print "empty" in test.pdf, can you help me again, sir? And can you solve my primary objective before, please?</p> <p>Thank you I am waiting for your reply</p> <p>Here's the link: <a href="http://www.mediafire.com/?0c043bhrgzqswff" rel="nofollow">dataSource, jrxml</a></p>
