я не могу получить txtpassword с этим Java-код:
DMTImplements imp=new DMTImplements();
Path parent = new Path("//pg_login/wlogin");
Textbox pass=(Textbox)new Path(parent,"txtPassword").getComponent();
Исключение сообщение:
Exception in thread "main" java.lang.NullPointerException
at org.zkoss.zk.ui.Path.getComponent0(Path.java:114)
at org.zkoss.zk.ui.Path.getComponent(Path.java:66)
что я должен делать ??
хорошо страницы идентификатор 'pg_index' и окно идентификатор' win_main' изменить свой второй ряд соответственно – AlexGreg
я имею в виду win_login извините, я хочу GetComponent() из win_login, который является txtPassword –
add login.zul тоже – AlexGreg
