><jsp:setProperty name="myBean" property="prepareParam"/>
><jsp:setProperty name="myBean" property="*"/>

>Hi all,
>
>I send some values of a html form (using post method) to a JSP page, which
>calls a JavaBean to actualize its properties (<jsp:setProperty
>name="myBean"
>property="*"/>).
>
>But when a field of the form is null (empty string in the form), the "set"
>method of the bean is not executed.
>
>Ex : in the form, the value of the field "toto" is changed from "aaa" to
>null : the setToto method of the bean is not called, and the value of the
>toto property is not actualized...
>
>A solution would really be appreciate :-)

>Many thanks,
