I have to send to the new modal dialog a parameter ( the username of the logged in user)


Code of the main controller :

public void onClick$bNewTestList(Event event)
throws SuspendNotAllowedException, InterruptedException, ClassNotFoundException, SQLException, NamingException {
HashMap map = new HashMap<String, String>();
String username = ((Label)page.getFellow("lUsername")).getValue();
map.put("username", username);


final Window dialog = (Window) Executions.createComponents( "WindowNewTestList.zul",null , map);
dialog.doModal();

...........................


The controller code of the new component :


....................

public void onClick$bSaveTL (Event event) throws NamingException, SQLException {
String username = (String)execution.getArg().get("username"); <<<----- here the arg map is empty !!!

TestList testList = new TestList();
testList.setTL_CREATOR(username);
testList.setTL_NAME(tTestListName.getValue());
testList.setTL_DESCRIPTION(tTestListDescription.getValue());
TestListDAO testListDAO= new TestListDAO();
testListDAO.addTestList(testList);
self.detach();
}

.....................

catch it in the afterCompose method of the modal window

	
        @Override
	public void doAfterCompose(Component window) throws Exception {
		super.doAfterCompose(window);

		if (arg.containsKey("username ")) {
			String s =  (String) arg.get("username"));
                        .  .  .

Terry,

Pardon my ignorance, where do you get the args from in the doAfterCompose?
When I call from one of my composer:

Window win = (Window) Executions.createComponents("/adduser.zul", userManagementWindow,
null);

win.setMaximizable(true);
try {
win.doModal();
} catch (SuspendNotAllowedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

And passing some arguments to this new zul page. How would I retrieve the arguments in the doAfterCompose of the new page?

Thanks in advance

Olivier

If you call super.doAfterCompose( comp ) from your doAfterCompose(...) in a GenericForwardComposer, the args variable is autowired for you. So, it will have all the values passed as the 3rd argument to Executions.createComponents(...).

like Cary said you can see the code in the GenericAutowireComposer from which the GenericForwardComposer inherits.

abstract public class GenericAutowireComposer extends GenericComposer
implements ComponentCloneListener, ComponentActivationListener {
	private static final long serialVersionUID = 20091006115726L;
	private static final String COMPOSER_CLONE = "COMPOSER_CLONE";

       . . .

	protected transient Map arg;
	/** Implicit Object; the param argument passed from the http request.
	 * @since 3.6.1
	 */

       . . .

.
It's the same as you do it manually like this

public class MyDialogCtrl extends GenericAutowireComposer implements Serializable {
       . . .

	public void onCreate$myDialogWindow(Event event) throws Exception {

		CreateEvent ce = (CreateEvent) ((ForwardEvent) event).getOrigin();
		Map<Object, Object> arg =   ce.getArg();
               . . .
