Use method using RootParamNode instead

Returns:

                             java.lang.String name,

                             java.lang.annotation.Annotation[] annotations)

Called when play need to bind a Java object from HTTP params. When overriding this method, do not call super impl.. super impl is calling old bind method to be backward compatible.

bind

@Deprecated
public java.lang.Object bind(java.lang.String name,
                                        java.lang.Object o,

Called when play need to bind an existing Java object from HTTP params. When overriding this method, DO NOT call the super method, since its default impl is to call the old bind method to be backward compatible.
