DirectLink in Abstract Component
Hi,
I have a menu component that extends AbstractComponent. It seems that my
DirectLinks in the menu component does not work. I have 4 different Listener
methods and I have injected the pages that they should go to. If I add
sysout:s to se if I end upp in the listener methods nothing happens. I have
done this:
in MenuComp.java:
public abstract class MenuSystem extends AbstractComponent {
/* */
@InjectState("sessionuserinfo")
public abstract SessionUserInfo getSessionUserInfo();
@InjectPage("HomeAction")
public abstract HomeAction getHomePage();
@InjectPage("ContactUsPage")
public abstract ContactUsPage getContactUsPage();
@InjectPage("ArticlePage")
public abstract ArticlePage getArticlePage();
@InjectPage("ArticleListPage")
public abstract ArticleListPage getArticleListPage();
@Override
protected void renderComponent(IMarkupWriter writer, IRequestCycle cycle) {
.....
writer.begin("a");
writer.attribute("jwcid", "@DirectLink");
writer.attribute("listener", "listener:onClickDirectLinkHomePage" );
writer.attribute("onmouseover", "hideAllButThis('none', 'none');");
writer.attribute("href", "#");
writer.begin("span");
writer.print(menu.getName());
writer.end(); // end span
writer.end(); // end a
....
}
public HomeAction onClickDirectLinkHomePage() {
return getHomePage();
}
public ContactUsPage onClickDirectLinkContactUsPage() {
return getContactUsPage();
}
public ArticleListPage onClickDirectLinkArticleListPage(Long menuId) {
getArticleListPage().setMenuId(menuId);
return getArticleListPage();
}
public ArticlePage onClickDirectLinkArticlePage(Long articleId) {
getArticlePage().setArticleId(articleId);
return getArticlePage();
}
}
The menu component is rendering correctly, but nothing happens when I try to
click on my DirectLinks. Hopefully I just missed something small, but I cant
see it...
Thanks
Jacob

Do you have any examples on how this works? I have realised that the way I
am trying to do it defenetly do not work.
writer.begin("a");
writer.attribute("jwcid", "@DirectLink");
writer.attribute("listener",
"ognl:listeners.onClickDirectLinkArticleListPage");
writer.attribute("parameters", menu.getMenuId().intValue());
writer.attribute("onmouseover", "hideAllButThis('pm_" + menu.getName()
+"Menu', none');");
writer.attribute("href", "");
writer.begin("span");
writer.print(menu.getName());
writer.end(); //end span
writer.end(); // end a
becouse I put in jwcid:s and ognl etc in already generated html.
So the question is how can I generate the link and add that to the writer?
Thanks
Jacob

The DirectLink component is not that complex: it uses the "direct"
service to create a link. When the user clicks on the link, the "direct"
service handles almost everything.
What you can do (for example) is to implement IDirect in your component
(which extends AbstractComponent) and generate a link using the "direct"
service which will trigger that component.
I recommend you to look at the source code of DirectComponent.
As I know you can define contained components in any component. So
another solution is to define a DirectLink in your .jwc file and
explicitly render it from the renderComponent() method of your custom
component.

Norbi

Please,
have anybody created a DirectLink in a Custom Component that extends from
AbstractComponent? How do you do that?
I could really need some pointers!
Thanks in advance,
Jacob
