HI Deepak,
please have a look at the below documentation :-
http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/corelib/components/BeanEditForm.html
2. You do not need the constructor explicitly defined I believe.
And this is with java, you do not need super in the parameterized constructor, that just calls object's constructor...which is implicit.
3.you can initialize the celebrity class in setup or begin render method of your addcelebrity.java, and everything should be fine.
Best regards
Akshay

Add this to AddCelebrity:

if (celebrity == null) {
celebrity = new Celebrity();
}
