I have a bean on a page, and the user may remove the value of an attribute by using the delete key to remove the contents of a pre-populated text box. On the following page we use <jsp:setProperty...property="*"> or <jsp:setProperty...property="firstName"> to set all the values. This works fine for everything apart from empty strings.
The approach I took to solving the same problem is to remove my session-scope bean and then re-instantiate it:
<%
session.removeAttribute("sRefQueryTerms");
%>
<jsp:useBean id="sRefQueryTerms" scope="session"
class="org.mdibl.ctd.jsp.beans.RefQueryTermsBean" />
<jsp:setProperty name="sRefQueryTerms" property="*" />I don't know how (in)efficient this is, but it didn't sound any worse than doing 15 setProperty calls setting strings to null (or "").
