a4j:commandButton incorrectly generated when rerendering ric

[bastian_knight]

I have a problem: when I rerender rich:dataTable then a4j:command... elements are incorrectly generated. They are wrongly connected with request scope variable, declared in rich:dataTable. Here is my example JSP:

<h:form>
<h:selectOneListbox value="#{BooksFormBean.selectedAuthor}">
 <a4j:support event="onchange" reRender="books" ajaxSingle="true"/>
 <f:selectItems value="#{AuthorsBean.authors}" />
</h:selectOneListbox>
<a4j:outputPanel id="books">
 <rich:dataTable var="Book" value="#{BooksFormBean.selectedAuthor.booksCollection}">
 <rich:column>
 <f:facet name="header"><h:outputText value="Title"/></f:facet>
 <h:outputText value="#{Book.title}" />
 </rich:column>
 <rich:column>
 <a4j:commandLink value="Add" actionListener="#{BooksFormBean.addActionListener}"
 ajaxSingle="true" />
 </rich:column>
 </rich:dataTable>
</a4j:outputPanel>
</h:form>

I expect that in action listener I can access var="Book" from faces context using following code:

Book added = (Book) FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("Book");

but the request scope variables are populated correctly only on the first rich:datatable rendering. After rerendering the table request scope variables aren't repopulated according to the new table state.

Is it an error in RichFaces or am I missing something?

can't reproduce under 3.3.0

I have tried the latest stable version and the latest 3.3.0 snapshot and I still encounter this issue. Maybe I should mention that the whole content of the table changes on selecting an option in the listbox.

I can provide the source code for my test case and WAR. I can upload it on my HTTP server on Monday.

I have uploaded a NetBeans project with my testcase. It is available at the following location:
http://www.eti.pg.gda.pl/katedry/kask/pracownicy/Michal.Piotrowski/RichTestCaseApplication.zip

Project includes compiled WAR in dist directory. In the test case I use latest stable version (3.2.2.SR1) but I have tested it with 3.3.0 snapshot and the effect was the same.

If you deploy the WAR on JBoss or Glassfish you can see that when you select "1st" in listbox and click a button in the first row of a table than in an application server log you see text "one". When you select in listbox "2nd" then after clicking button in the first row there will be "one" in the server log and after clicking button in the second row there will be "null" in the server log but there should be "two" and "three" printed in the log.

I have tested it on Linux with JDK 6.0_11 on Glassfish 2 and JBoss 4.2.3, Firefox 3 and Konqueror 4.1

change the scope of your bean to session or at list add keepAlive for ajax requests in this case for this bean.
