Hi all !

Im trying to open a new tab when doubleClicking a row in a listbox, and include a zul in the tabPanel contained in that tab.

When i Want to call the zul, I get a null exception, and dont know why.. any suggest??

 @Command
    public void onDoubleClicked(@BindingParam("tabPanel") Tabbox tabPanel) {

	this.tabBox = tabPanel;
	Map<String, Integer> arguments = new HashMap<String, Integer>();
	arguments.put("prim", 1);
	String le = selectedUser.getFull_name();
	Tab newTab = new Tab(le);
	newTab.setSelected(true);
	newTab.setClosable(true);
	newTab.setParent(tabPanel.getTabs());
	Tabpanel newTabpanel = new Tabpanel();
	Executions.createComponents("Alta.zul", newTabpanel, arguments);  // <----- This causes exception
	//newTabpanel.appendChild(new Label("New Tabpanel Text "));
	newTabpanel.setParent(tabBox.getTabpanels());

    }
