Re: JSCookMenu actionListener

[Thomas Spiegl]

Hi,

I sent this email a few days ago ...

I implemented the actionListener for JSCookMenu. Get the latest
version from SVN or use nightly build to get the new feature.
Attached you will find an example.

1) Example 1  Static
<t:navigationMenuItem id="nav_2"
    actionListener="#{navigationMenu.actionListener}"
    itemLabel="#{example_messages[
'nav_Home']}"
    itemValue="go_home"
    action="go_home"/>
The actionListener JSCookMenuBean.actionListener(ActionEvent event)
will be executed. HtmlCommandJSCookMenu is now holding the itemValue
of the clicked menu entry. Additionaly the action attribute may be
given to trigger a page navigation.

2) Example 2 Dynamic
Shows how to generate menu items 'dynamically' by using
NavigationMenuItem(s) + how to define an ActionListener per item (see
JSCookMenuBean.getJSCookMenuNavigationItems())
The actionListener JSCookMenuBean.actionListener(ActionEvent event)
will be executed. HtmlCommandJSCookMenu is now holding the value that
was set for the NavigationMenuItem (see
JSCookMenuBean.getMenuNaviagtionItem(...))

Cheers
Thomas
