if nested property is null

Hello,
i have a nested property  that i display in the jsp page :
<nested:nest property="iee">

                                <nested:write property="intaffIee" />
                            </nested:nest>
                        </nested:nest>
but , i can have a null value of iee property
how can i implement this to avoid an exception such as this one in the jsp
page :

javax.servlet.jsp.JspException: Invalid argument looking up property

Regards
Elyes.
