> from: [jsr-314-open] Ajax inside a DataTable
> Cagatay Civici
> I've faced with an issue in our app I'd like to share when trying to update
> the datatable itself from a command element located inside a column. Case is
> to select a row, execute logic and update the datatable. Basic code:
> <h:dataTable id="cars" var="car" value="#{tableBean.carsSmall}">
> <h:column>
> <f:facet name="header">
> Model
> </f:facet>
> <h:outputText value="#{car.model}" />
> </h:column>
> <h:column>
> <f:facet name="header">
> Action
> </f:facet>
> <h:commandButton value="Some Action"
> actionListener="#{tableBean.handleRowAction(car)}">
> <f:ajax render="cars" />
> </h:commandButton>
> </h:column>
> </h:dataTable>
> As datatable has a rowIndex >= 0 during rendering of commandButton f:ajax
> defines the component id to render as cars:{rowIndex} where I should expect
> "cars" only. This is due to UIData.getClientId implementation as UIData
> adds rowIndex for unique row ids. This causes an issue with a nested f:ajax
> case.
> Martin Marinschek
> We should never include the row-index in the client-id of the table
> itself. For this, we need to revise the client-id generation
> algorithm.
> Without actually having tried it, I think that it is easy to do so, as
> we have a UIComponentBase.getContainerClientId() to create the
> client-id of the children - when this method is called, we append the
> row-index, if getClientId() itself is called, we don´t.
