Yeah, we considered this however the bean already contains objects which are not strings (dates and so on..) so we cant remove it from the session. If everything was a string in the bean you could put it in the form as a hidden value. This is a bit fo a nasty hack anyway. At the moment we are using the '15 setProperty calls setting strings to ""' approach! There must be another way? Thanks anyway. I'm pleased to hear others have the same problem.

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 ""). /mcr =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
