    <p>I have a column called <code>totalhours</code> in my report where I want to set back color to <code>yellow</code> when value of column called <code>outtime</code> is <code>null</code>. So for that i have created a conditional style with following details :</p> <pre class="lang-xml prettyprint-override"><code>&lt;style name="TotalHoursBackColor" lineSpacing="Single"&gt; &lt;conditionalStyle&gt; &lt;conditionExpression&gt;&lt;![CDATA[new Boolean($F{Out_time}.equals( null ))]]&gt; &lt;/conditionExpression&gt; &lt;style mode="Opaque" backcolor="#FFFF33" lineSpacing="Single"/&gt; &lt;/conditionalStyle&gt; &lt;/style&gt; </code></pre> <p>The above code gives the following output</p> <pre> SlNo. empid intime outime totalhours 1 100 9:00 13:00 4:00 2 101 9:10 null yellow 3 105 9:30 13:30 14:30 null 4 103 9:30 18:30 9:00 5 107 9:40 13:40 8:00 14:40 18:40 6 108 10:00 null yellow 7 106 10:00 13:00 14:00 null </pre> <p>But, I want the output as follows :</p> <pre> SlNo. empid intime outime totalhours 1 100 9:00 13:00 4:00 2 101 9:10 null yellow 3 105 9:30 13:30 yellow 14:30 null 4 103 9:30 18:30 9:00 5 107 9:40 13:40 8:00 14:40 18:40 6 108 10:00 null yellow 7 106 10:00 13:00 yellow 14:00 null </pre> <p>Please find the jrxml file :</p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
