[jboss-user] [JBoss Seam] - T or F? - <s:link/> in dataTable must use @DataModel or REST
Just a simple yes or no question. From my reading about s:link it looks like if you want
to use it in a clickable list you must either use it conjunction with the @DataModel
annotation in your session bean or you must use a RESTful approach by sending in the id of
the component on the list and look it up again on the server side.
I found that if I used s:link in a dataTable it did not inject the object in the DataTable
into the session bean. Once I changed the link to an <h:commandLink> the selected
object on the data table would be properly injected into my session bean.
This injects the selected object from datatable:
<h:commandLink value="Edit"
action="#{officeTransmittalAction.editClientTransmittalLineItem}" />
This does not inject the selected object from the datatable without @DataModel
<s:link value="Edit"
action="#{officeTransmittalAction.editClientTransmittalLineItem}" />
<rich:dataTable value="#{clientTransmittal.lineItemsList}"
| var="lineItem"
| rendered="#{not empty clientTransmittal.lineItemsList}"
| rowClasses="rvgRowOne,rvgRowTwo"
| id="countytranslineitemsesTable">
|
| <h:column>
| <f:facet name="header">description</f:facet>
| <h:outputText value="#{lineItem.description}" />
| <rich:spacer />
| </h:column>
| <h:column>
| <f:facet name="header">
| <rich:spacer />
| </f:facet>
| <h:commandLink value="Edit"
| action="#{officeTransmittalAction.editClientTransmittalLineItem}"
/>
| </h:column>
| </rich:dataTable>
@Stateful
| @Name("officeTransmittalAction")

| public class OfficeTransmittalsActionImpl implements OfficeTransmittalsAction {

"lineItem")
