JSCookMenu and passing value to manged-bean

Hi!

Thanks for the answer. It helped me a lot. At the beginning i thought that the following code:

String categoryId = (String) command.getValue();

would have returned a label value. But after testing it turned out that my predictions were wrong.

Below I put my code maybe it will be useful for somebody. Once again thank you.

Regards,

Mariusz

I'd like to call a function of a managed bean. I did like that but the function isn't called.

Here is the code of the managed bean:

public ArrayList<NavigationMenuItem> getNavItems()

{

ArrayList<NavigationMenuItem> menu = new ArrayList<NavigationMenuItem>();

// layers

ArrayList<NavigationMenuItem> layerItems = new ArrayList<NavigationMenuItem>();

Iterator it = layers.iterator();

while (it.hasNext())

{

WebigeoLayer webigeoLayer = (WebigeoLayer) it.next();

NavigationMenuItem layerItem = new NavigationMenuItem(webigeoLayer

.getAliasName(), null, "./images/galigeo/new_ana.gif",

false);

ArrayList<RendererAssistant> renderers = webigeoLayer

.getRenderers();

if (renderers.size() > 0)

{

ArrayList<NavigationMenuItem> rendererItems = new ArrayList<NavigationMenuItem>();

Iterator it2 = renderers.iterator();

while (it2.hasNext())

{

RendererAssistant renderer = (RendererAssistant) it2.next();

NavigationMenuItem rendererItem = new NavigationMenuItem(

renderer.getTitle(), null);

if (renderer.isEnabled())

rendererItem.setIcon("./images/galigeo/checked.gif");

else

rendererItem.setIcon("./images/galigeo/unchecked.gif");

rendererItem.setValue(renderer.getId());

rendererItem

.setActionListener("#{rendererList.enableRendererFromSmallMap}");

rendererItems.add(rendererItem);

}

layerItem.setNavigationMenuItems(rendererItems);

}

layerItems.add(layerItem);

}

ResourceBundle rb = ResourceBundle.getBundle("i18n/messages");

NavigationMenuItem menuItem = new NavigationMenuItem(rb

.getString("renderers"), null);

menuItem.setNavigationMenuItems(layerItems);

// root items

menu.add(menuItem);

return menu;

}

public void enableRendererFromSmallMap(ActionEvent event)

throws AbortProcessingException

{

HtmlCommandJSCookMenu command = (HtmlCommandJSCookMenu) event

.getSource();

String id = (String) command.getValue();

System.out.println("id : " + id);

}

Here is the code of the jsp:

<td align="left"><t:jscookMenu layout="hbr" theme="ThemeIE">

<t:navigationMenuItems value="#{rendererList.navItems}" />

</t:jscookMenu></td>
