Hi,
I get the following warning message when trying to retrieve a localized
string: *Tried to retrieve a localized string for a component that has not
yet been added to the page. This can sometimes lead to an invalid or no
localized resource returned. Make sure you are not calling
Component#getString() inside your Component's constructor. Offending
component*
This how my code look like:
public class NavigationBarPanel extends Panel {
private static final long serialVersionUID = 1L;
/** The navigation bar links */
private final String MENU_MENU = new
StringResourceModel("navigationbar.menu.home", this, null).getString();
private final String NUMBER_POOL_MENU = new
StringResourceModel("navigationbar.menu.numberpool", this,
null).getString();
private final String NUMBER_POOL_LOG_MENU = new
StringResourceModel("navigationbar.menu.numberpoollog", this,
null).getString();
private final String DEFRAGMENT_MENU = new
StringResourceModel("navigationbar.menu.defragment", this,
null).getString();
private final String SEARCH_MENU = new
StringResourceModel("navigationbar.menu.search", this, null).getString();
public NavigationBarPanel(String id) {
super(id);
addLinks();
}
private void addLinks() {
addLink("home", MENU_MENU, HomePage.class);
addLink("numberPool", NUMBER_POOL_MENU, NumberPoolPage.class);
addLink("numberPoolLog", NUMBER_POOL_LOG_MENU,
NumberPoolLogPage.class);
addLink("defragment", DEFRAGMENT_MENU, DefragmentPage.class);
addLink("search", SEARCH_MENU, SearchPage.class);
}
private void addLink(String id, String title, final Class<? extends
Page> pageClass) {
BookmarkablePageLink link = new BookmarkablePageLink(id, pageClass);
link.add(new AttributeModifier("class", true, new
AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;
@Override
public Object getObject() {
String currentPageName = pageClass.getName();
String parentPageName = getPage().getClass().getName();
return StringUtils.equals(currentPageName, parentPageName) ?
"current_page_item" : AttributeModifier.VALUELESS_ATTRIBUTE_REMOVE;
}
}));
link.add(new Label("title", new Model(title)));
add(link);
}
}
Could you please tell me why am I getting this warning. I use the same
strategy to add localized string to my pages but I don't get warnings.
