Datatable delete last row problem

[iimirela]

Hello, I seem to have a problem with the datatable. It does not delete the last row. Well actually it does, because if I navigate to another page, and come back, the table is gone.

<rich:dataTable id="servicesTable" value="#{GestioneServiziBean.serviceList}" var="service" reRender="ds"
 rows="7" width="100%" rowKeyVar="row">
 <!-- headers -->
 <f:facet name="header">
 <rich:columnGroup>
 <rich:column >
 <h:outputText value="#{pageMessages.labelDescrizione}" styleClass="headerText" />
 </rich:column>
 <rich:column >
 <h:outputText value="#{pageMessages.labelDipendenza}" styleClass="headerText" />
 </rich:column>
 <rich:column>
 </rich:column>
 <rich:column>
 </rich:column>
 </rich:columnGroup>
 </f:facet>

 <!-- descrizione -->
 <rich:column filterBy="#{service.descr}" filterEvent="onkeyup">
 <rich:inplaceInput value="#{service.descr}" layout="block" viewClass="inplace" />
 </rich:column>

 <!-- dipendenza -->
 <rich:column styleClass="calign" filterBy="#{service.parent.descr}" filterEvent="onkeyup">
 <rich:inplaceSelect value="#{service.parent.id}"
 layout="block" viewClass="inplace" openOnEdit="true">
 <f:selectItems value="#{GestioneServiziBean.listaDipendenze}" />
 </rich:inplaceSelect>
 </rich:column>

 <!-- salva -->
 <rich:column styleClass="calign" width="30">
 <f:facet name="header"></f:facet>
 <a4j:commandLink action="#{GestioneServiziBean.saveService}" reRender="servicesTable">
 <h:graphicImage styleClass="icon" url="/images/conferma.png" />
 <f:setPropertyActionListener value="#{row}" target="#{GestioneServiziBean.selIndex}"/>
 </a4j:commandLink>
 </rich:column>

 <!-- elimina -->
 <rich:column styleClass="calign" width="30">
 <f:facet name="header"></f:facet>
 <a4j:commandLink action="#{GestioneServiziBean.deleteService}" reRender="servicesTable">
 <h:graphicImage styleClass="icon" url="/images/delete.png" />
 <f:setPropertyActionListener value="#{row}" target="#{GestioneServiziBean.selIndex}"/>
 </a4j:commandLink>
 </rich:column>

 <!-- pagination -->
 <f:facet name="footer">
 <rich:datascroller id="ds" renderIfSinglePage="false" />
 </f:facet>
 </rich:dataTable>

hi there,

is the table or the row gone after you navigate back to your page with the table?

well, i too have a column for deleting the selected line. but i'm doing this with an actionListener. you can get to the dataTable over the action event, get the rowdata and delete the row. works fine for me.

The table is gone. I somehow deleted a very important detail in the code

rendered="#{!empty GestioneServiziBean.serviceList}"

so when the list is empty the table is not rendered. I debuged the whole thing, the delete method is called, the collection becomes empty, it's just the table that is not reRendered.

well, i think your model gets updated correctly as you said. but in the render response phase, where your table should be rendered, the table won't be rendered because your list is empty. and by getting the rendered attribute value from your backing bean there will always be rendered="false".

anyone, correct me if i'm wrong.

rendered="#{!empty GestioneServiziBean.serviceList}"

you should not reRender conditionally rendered elements directly. reRender its parent.

Brilliant! Worked like a charm.
