  • defaultApplicationPagePrototype can not be created

    I am trying to declar my own page prototype, for that i created bean
    defaultApplicationPagePrototype in sample applications - richclient-startup-context.xml - but found that it can not be created due to code in createPage function which creates the Bean of type DefaultApplicationPage...

    -->> From DefaultApplicationWindow.java
    protected ApplicationPage createPage(PageDescriptor descriptor) {
    try {
    DefaultApplicationPage page = (DefaultApplicationPage)getServices().getBean(
    DEFAULT_APPLICATION_PAGE_BEAN_ID, DefaultApplicationPage.class);
    page.setApplicationWindow(this);
    page.setDescriptor(descriptor);
    return page;
    }
    catch (NoSuchBeanDefinitionException e) {
    return new DefaultApplicationPage(this, descriptor);
    }
    }


    -->> From AbstractApplicationPage.java
    public AbstractApplicationPage(ApplicationWindow window, PageDescriptor pageDescriptor) {
    setApplicationWindow(window);
    setDescriptor(pageDescriptor);
    }

    ...
    public final void setApplicationWindow(ApplicationWindow window) {
    Assert.notNull(window, "The containing window is required");
    Assert.state(this.window == null, "Page window already set: it should only be set once, during initialization");
    this.window = window;
    sharedCommandTargeter = new SharedCommandTargeter(window);
    addPageComponentListener(sharedCommandTargeter);
    }




    Now DefaultApplicationPage constructor expects two argument and sets applicationWindow and throws Illigal ArgumentException if setApplicationWindow is called again. So theoritically you can not use "DefaultApplicationWindow" without over riding this method.

    I am wondering how others change their page layout for adding addtional docable windows - alwyas extend "DefaultApplicationWindow" and over-ride above protected ApplicationPage createPage(PageDescriptor descriptor) method?
Working...
