AW: Define Trinidad navigation in faces-config.xml using action
methods instead of outcomes
Hello Stefan,
Thanks for the hint regarding .AFRequiredIconStyle.
I also got my menu to work now. For everyone who is interested in the solution:
I developed a managed bean doing the conversion for me:
<managed-bean>
<managed-bean-name>method</managed-bean-name>
<managed-bean-class>de.tccproducts.kn.jsf.util.ActionBindingConverter</managed-bean-class>
<managed-bean-scope>none</managed-bean-scope>
</managed-bean>
I can reference this bean's getBinding method in the navigation items as MethodBinding
<managed-bean>
<managed-bean-name>mtn_kape_createKeyAccount</managed-bean-name>
<managed-bean-class>de.tccproducts.kn.jsf.model.MenuTreeNode</managed-bean-class>
<managed-bean-scope>none</managed-bean-scope>
<managed-property>
<property-name>action</property-name>
<property-class>javax.faces.el.MethodBinding</property-class>
<value>#{method.binding['keyAccountProfileEditorController.showCreateKeyAccount']}</value>
</managed-property>
[...]
The code of the ActionBindingConverter:
public class ActionBindingConverter {
private MethodBinding getMethodBinding(String methodName) {
return FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{" + methodName + "}", null);
}
public Map<String, MethodBinding> getBinding() {
return new HashMap<String, MethodBinding>() {
private static final long serialVersionUID = 0L;
@Override
public int size() {
return 1;
}
@Override
public MethodBinding get(Object key) {
return getMethodBinding((String) key);
}
};
}
}
Regards
Jochen

I'm not sure if I got you right. But I guess it would be a good idea
creating the getAction() method in your MenuTreeNode class instead of
the keyAccountProfileEditorController. The MenuTreeNode would just
delegate to the appropriate controller (which has been injected
before) based on its configuration through its properties.
As for the required icon, you can hide it easily by adding the
following stylesheet:
.AFRequiredIconStyle {display:none;}

I want to use the approach to have the navigation hierarchy configured in the facelets-config.xml as a tree of managed beans describing the label and action of the menu items. This way I can easily use components like <tr:breadCrumbs> to render the way the user walked down the navigation path.

But even if I switch all navigation items to the session scope I get exceptions because the engine tries to evaluate the expression as a bean property and not as a method binding. So the engine tries to find a method getShowSearchKeyAccount in my controller bean. Is there a workaround to realize what I want to do or do I have to rethink about my design.
