Sorry, you did say that.-)
But I was looking at this "<html:text
property="mailingAddress.street"/> mailingAddress is null?", which
implied that the property may be edited.
For display only, you may wish to use the <bean:write > tag, which does
not render output when the property is null.

Hello Ted,
Thanks for your response.
However, I made a distinction between displaying fields of a Model bean
on a
JSP and updating or creating a Model bean on a JSP. For updating or
creating
a Customer an initialized deliveryAddress should be there in the Form
Bean,
no doubt about this.
Note that the Struts framework makes the same distinction: only for
updating
or creating Model beans a Form Bean is needed (so for HTML Forms).
However, when I want to display the fields of a Model bean I do not
like to
change the Model bean. In our application we use Entity Beans (EJB),
and
Entity beans can have a deliveryAddress with value null (when the
foreign
key relating a deliveryAddress to a Customer in the Customer table is
null).
Regards, Arjan.
