Hello Everybody,

I have just started to use StrutsMenu. Its really gr8 thing.

While development to adjust my requirement I have added few things which I whould like to share with you all.

1) Generating MenuComponent Object dynamically.
MenuComponentBuilder is a utility class that can generate the MenuComponent from any object. This will help to provide dynamic Menus in web application.
[ attachments MenuComponentBuilder.java, Test program TestObj.java ]

2) Hook in MenuDisplayer.
I had a requirement by which on certain business conditions few MenuComponets where not supposed to be shown to user. For this I have
- Added an iterface called MenuObjectValidator.
- Modified BaseMenu to store the object from which the MenuComponent is generated.
- Modified UseMenuDisplayerTag to accpent implementation of MenuObjectValidator and set on displayerInstance; and this instance should call validate method on impl before processing a MenuComponent to be displyed.

Please let me know your suggestions on it.
