Hi guys,
I have a very strange problem with jasperreport.
I'm working on fedora 9, with jdk5.15 and zkoss3.0.4 (but the problem remains also with 3.0.6 and 3.0.7)
I have a window with this line

<jasperreport id="jr" visible="false"/>

Clicking on a button in this window, this code is called:

	public void onStampa()
		String[] cart = (String[])getNamespace().getVariable("datiCart", true);
		Date dallaData=(Date)getNamespace().getVariable("dallaData", true);
		SimpleDateFormat df=new SimpleDateFormat("MM/yyyy");	
		if (cart != null)
			System.out.println("not null");

                       //print details
			for (int i = 0; i< cart.length; ++i)
				System.out.println(cart<i >);
			String body = "";
			for (int i = 3; i< cart.length; ++i)
				body += cart<i > + "\n";
			Cartolina c = new Cartolina(cart[0], cart[1], cart[2], body, df.format(dallaData));
			ArrayList<Cartolina> coll = new ArrayList<Cartolina>(0);
			JRDataSource ds = new JRBeanCollectionDataSource(coll);
			Jasperreport report = (Jasperreport)getFellow("jr");

			ICHelper.Messaggia("Cartolina vuota");

at the end of this piece of code execution I have on the console:
not null

The code is executed from the beginning to the end, but nothing happens.
No window is opened to save or open a pdf file, no errors, nothing!

Can anybody help me?

Hi twain:

Would you like to tell us your onStampa() function is running in Java or zscript?

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"

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);
		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}"/>

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?
