FW: multipart/form-data problem

[markus.colombo]

It seems that no user experienced this problem before?

So I thought I'll ask the question on the dev list before trying to dig into
the source code of struts...

Is there a known limitation/problem with request attributes together with
multipart/form-data forms?

Thanks

Markus

Subject: multipart/form-data problem


Hi,

we implemented a JSP with a multipart/form-data form.
Everything seems to work fine except in the case when our form returns an
error on validation. We have a request parameter (GPKUpdate) to tell if we
do a update to an existing record or if we add a new record.
When our form bean adds an error during validation and the Entryform is
(should be) displayed again, the parameter is missing from the request:

Root cause of ServletException
javax.servlet.jsp.JspException: No parameter GPKUpdate was included in this
request
        at
org.apache.struts.taglib.template.InsertTag.doEndTag(InsertTag.java:149)

If we remove the enctype='multipart/form-data' attribute of the form (and
the html:file tag) error handling is working.

Are we missing something? It seems that the request parameters get lost in
case of an error in validation, but only when using
enctype='multipart/form-data' ?

We tried with 1.0 and the nightly build with the same effect.

Thanks for any input

Here is the relevant code of our .jsp file:


<%@ page language="java" %>
<%@ taglib uri="/struts-html.tld" prefix="html" %>
<%@ taglib uri="/struts-logic.tld" prefix="logic" %>
<%@ taglib uri="/struts-bean.tld" prefix="bean" %>

<bean:parameter id='GPK2Update' name='GPKUpdate'/>
<font color='red'><html:errors/></font><br>
<center>
<html:form action="articleEntry" enctype='multipart/form-data'

<html:hidden property="GPKUpdate"/>
<table width="100%" cellspacing="0" cellpadding="0">

  <td width="30%">
<bean:message key="articleEntry.articleQTY"/>
  </td>
  <td>
