Read Value of a NamedExpression

haglo

<div>I use eclipse 4.4.1, windows 8.1, java 7 and birt 4.4.1.<br>
I want to make all in java.</div>
<div> </div>
<div>I have a report with a table.</div>
<div>In the table footer I add a Data. Then, in Data Binding, the Expression</div>
<div>Total.sum(row["Column Binding_5"]) with DataType float</div>
<div>In the "Property Editor - Data" I set the name to "Summe"</div>
<div> </div>
<div>I added a TableEventHandler to the table with the following Code</div>
<div> </div>
<div>
<pre class="_prettyXprint _lang-">
public void onRender(ITableInstance arg0, IReportContext arg1)
throws ScriptException {
float tmp = (float) arg0.getNamedExpressionValue("Summe");
if (tmp > 100.0) {
arg0.getStyle().setBackgroundColor("red");
}
}
</pre>
</div>
<div>My Question:</div>
<div>What is here wrong.</div>
<div>It happens nothing.</div>

<p>Could you elaborate on nothing happening.</p>
<p> </p>
<p>Does the code run at all or is not being executed?<br>
Do you see your variable tmp getting populated with a value?</p>
<p> </p>
<p>In your if statement, if you examine the output of arg0.getStyle().getBackgroundColor() before an after you set it do you see it changing to "red" like you want?</p>
