Hi

I tried converting my standard datatable into a rich:datatable.
I'm using Seam 1.2.1GA with myfaces

I have a simple CRUD page with all records in a datatable, one of the cols in is a name(hyperlink) and the other a disabled checkbox pointing to this

@Column (name="active", nullable=false, length=1)
@Type(type="yes_no")
private boolean active;

in my hibernate entity. When the name link is clicked, a detail form allows edit and when a save button is pressed, the name & checkbox in the list should reflect changed values. The name reflects changes but not the checkbox. The other problem (if I use the rich:datatable) is that multiple updates to the same row causes javax.persistence.OptimisticLockException - Note if I do not have the rich:datatable in my page, I don't see this problem.

This is the code for standard and rich datatables

 <h:dataTable id="catalogs" var="_catalog" value="#{catalogs}"
 styleClass="listing" columnClasses=",,fixed,,actions" footerClass="hide" rendered="#{not empty(catalogs)}" >
 <f:facet name="footer">
 <!-- -->
 </f:facet>

 <h:column>
 <f:facet name="header">Catalog Name</f:facet>
 <h:commandLink value="#{_catalog.name}" action="#{catalogList.select()}"/>

 </h:column>
 <h:column>
 <f:facet name="header">Active</f:facet>
 <h:selectBooleanCheckbox id="activeflag" value="#{_catalog.active}" disabled="true" />
 </h:column>

 </h:dataTable>

<-- rich datatable with same cols as standard dattable above -->
 <rich:dataTable id="dtCatalogList"
 onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
 onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
 cellpadding="0" cellspacing="0" width="500" border="0"
 var="_catalog" value="#{catalogs}" rendered="#{catalogs.rowCount>0}">

 <f:facet name="header">
 <rich:columnGroup>
 <rich:column>
 <h:outputText value="Catalog Name" />
 </rich:column>
 <rich:column>
 <h:outputText value="Active" />
 </rich:column>

 </rich:columnGroup>
 </f:facet>

 <rich:column> <h:commandLink value="#{_catalog.name}" action="#{catalogList.select()}"/></rich:column>
 <rich:column align="center" > <h:selectBooleanCheckbox value="#{_catalog.active}" disabled="true" /></rich:column>


 </rich:dataTable>

This is my table definition (Oracle) if that matters

CREATE TABLE CATALOG
(
 CATALOG_ID NUMBER(19) NOT NULL,
 CATALOG_NAME VARCHAR2(200 CHAR) NOT NULL,
 ACTIVE CHAR(1 BYTE) DEFAULT 'N',
 OBJ_VERSION INTEGER
)

This is my Seam components in SFSB which work fine with standard datatable.

 @PersistenceContext
 private EntityManager em;

 @DataModel
 private List<Catalog> catalogs;


 @DataModelSelection
 @Out(required=false)
 @In (required=false)
 private Catalog catalog ;

I'm sorry my misstated something - the disabled checkbox in the rich:datatable does not reflect a change immediately after an update. When i click that name link or any other name link row, the value displays correctly.

Perhaps i don't understand how to use it correctly.

This is my detail form

<rich:panel id="pnlCatalogDetail" rendered="#{showDetail eq true}">

 <table> <!-- class="detail" -->
 <colgroup>
 <col width="20%" />
 <col width="80%" />
 </colgroup>
 <tr>
 <th><h:outputLabel for="catalogName" value="Catalog Name" /></th>
 <td>
 <h:inputText id="catalogName" value="#{catalog.name}" size="40" maxlength="200" > </h:inputText>
 </td>
 </tr>
 <tr>
 <th><h:outputLabel for="catalogActive" value="Activate ?" /></th>
 <td>
 <h:selectBooleanCheckbox id="catalogActive" value="#{catalog.active}" />
 </td>
 </tr>


 </table>
 <h:commandButton value="Save" action="#{catalogList.save()}" /> #{spacer}
 <h:commandButton value="Cancel" action="#{catalogList.cancel()}" />
 </rich:panel>

Do I need to use a4j:commandButton for save
and reRender the datatable ?

You should use ajax action components - in the same way as standard ones.

The only differences is - you need to reRender affected areas, and you can optimize the request by ajax related attributes.
