I'm sorry for the missing detail, it runs in java.
This is the page code:

<?xml version="1.0" encoding="UTF-8"?>
<window Title="Cartolina" id="wCartolina_${arg.wndId}" use="it.aliaslab.infocert.listener.CartolineUI" sizable="true" closable="true" border="normal" contentStyle="background:#F2F4F1; overflow:auto; position:relative" position="center,center" width="900px" height="600px"
xmlns:a="http://www.zkoss.org/2005/zk/annotation" >
<?init class="it.aliaslab.infocert.TestLogin"?>
<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit"?>
<separator id="trg"/>
<separator />
<hbox>
<!-- label value="Intervallo per stampa dal" width="100px" /-->

</hbox>
<separator bar="true"/>
<grid width="98%" height="500px" model="@{datiCart,load-when=trg.onBeanListChange}">
<rows>
<row self="@{each=cart}">
<label pre="true" style="font-family:monospace; font-size:x-small" value="@{cart}" width="95%"/>
</row>
</rows>
</grid>
<jasperreport id="jr" visible="false"/>
<popup id="Stampa">

</hbox>
</popup>
</window>

I'm sorry for this question, it has been a stupid error.
With the visible = false it is really difficult to see anything.

But now I have another problem, using firefox 3 (with IE all works fine) and this code

(function in Java, and not in zscript, called when I click a button in a window)

	public void onStampa()
	{
               //fil the coll ArrayList
			
	        JRDataSource ds = new JRBeanCollectionDataSource(coll);

		getDesktop().getSession().setAttribute("ds", ds);
		Window w = (Window)Executions.createComponents("reports/dipendenti.zul", null, null);
			
		try 
		{
			w.doModal();
		} 
		catch (SuspendNotAllowedException e) 
		{
			ICHelper.Messaggia("Impossibile aprire la finestra dipendenti.zul");
			ICHelper.LoggaEccezione("Impossibile aprire la finestra dipendenti.zul", e);
		} 
		catch (InterruptedException e) 
		{
			ICHelper.Messaggia("Impossibile aprire la finestra dipendenti.zul");
			ICHelper.LoggaEccezione("Impossibile aprire la finestra dipendenti.zul", e);
		}
	}

dipendenti.zul is simply

<?xml version="1.0" encoding="UTF-8"?>
<window contentStyle="background:#F2F4F1; overflow:auto; position:relative" 
		position="center,center" title="Dipendenti" closable="true"
		sizable="true" border="normal" height="580px" width="800px">
    <jasperreport src="reports/dipendenti.jasper" datasource="${ds}"/>
</window>

I see a blank window only for the first time after the application deploy(JBoss 4.2.2). Window resize let the pdf appears inside it.
Only for the first time, if I try again all goes well.
Furthermore, when I close dipendenti.zul I have this error:

The code above is only an example. These probleme happen any time I use JR to obtain a PDF with firefox.
Any suggestion?
