I've been trying to resolve this problem for 2 days now.

My environment : RichFaces 3.1.6, Sun RI JSF 1.1, Tomcat 5.5 ( Use WL 9.2 for production)

To put it simply:
Step 1: I have a multiselect list in column10. I select a value and click on the DELETE button just next to the list. I also reRender column10 and column9. Works fine. Item gets deleted.

Step 2:When I click on DELETE button again, without selecting anything, the item I deleted previously re-apppears.

Step 3 : Restart scenario in DEBUG mode. When I run Step 1 again, the state of myBean is correct (i.e. the item is removed).
But when I do Step 2, myBean has still got the previously removed item !

Why is this ? Is this anything to do serialization with saveState still containing the previous state of myBean ??

Here's my code :

<h:form id="offerBillingCodeForm">
 <t:saveState id ="myBean" value="#{myBean}" />

 <!-- Lots of code here -->

 <rich:dataTable id="tableId" width="100%" border="1"
 value="#{myBean.myList}" var="aRow" rowKeyVar="rkv">

 <!-- Some columns here - of no significance -->

 <rich:column id="column9" style=" width: 60px;">
 <f:facet name="header">
 <h:outputText value="COLUMN WITH SUGGESTION BOX " />
 </f:facet>
 <h:inputText ... id="someId" style=" width: 40px;" />
 <a4j:commandButton id="buttonId" value="Add" eventsQueue="someQueue"
 action="#{myBean.someAction}"
 reRender="column9">
 <f:setPropertyActionListener value="#{rkv}" target="#{myBean.selectedRowIndex}" />
 </a4j:commandButton>
 <rich:suggestionbox id="suggestionBoxId2" for="someId"
 suggestionAction="#{offerBillingCodeAssnBean.suggestBillingCode}" var="billingCode"
 ......>
 ....

 </rich:suggestionbox>
 </rich:column>

 <rich:column id="column10" rendered = "true" style="width: 140px;">
 <f:facet name="header">
 <h:outputText value="COLUMN THAT SHOWS THE ADDED SUGGESTIONS FROM COLUMN 9" />
 </f:facet>
 <h:selectManyListbox id="listId" value="#{aRow.selectedArr}" size="3" style="width: 140px;">
 <f:selectItems value="#{aRow.selectItemList}" />
 </h:selectManyListbox>
 <a4j:commandButton id="deleteButton" value="Remove Suggested Value" eventsQueue="someQueue"
 action = "#{myBean.removeSuggestion}"
 reRender="column9,column10,">
 <f:setPropertyActionListener value="#{rkv}" target="#{myBean.selectedRowIndex}" />
 </a4j:commandButton>
 </rich:column>

 <!-- more columns -->

 <rich:dataTable>
</h:form>
