How to get selected row from dataTable

[satyakatti]

Hi All,

I needed to get the selected row from a rich:dataTable .

I found many suggestions from previous posts and implemented one, but that is  not working.

Here is the discussion which I referred : http://community.jboss.org/message/21533#21533

And my code :

<rich:dataTable id="idChannelsExtTable"
                value="#{channelsBean.channelsList}"
                binding="#{channelsBean.dataTable}"
                var="channelAttr" sortMode="single">

     <rich:column sortable="false" label="Generation Parameters">

       <f:facet name="header">

          <h:outputText value="Generation Parameters" />
         </f:facet>
         <h:outputText value="#{channelAttr.generationParameters}" />
     </rich:column>

          -

          -

          -

<a4j:support event="onRowDblClick" requestDelay="400" actionListener="#{channelsBean.editDataItem}" ajaxSingle="true" />

</rich:dataTable>

and backing bean as :

private UIDataTable dataTable;

public void editDataItem(ActionEvent event) {
        log.info("selected row index : " + getDataTable().getRowIndex());
    }

PS: Backing bean is session scoped.

Also the whole flow is : I have a rich:comboBox which retrieves the data for above said rich:dataTable.

When I double click on a row, method to retrieve dataTable is called but not the method which intends to capture clicked row index i.e editDataItem.

in that case the simplest would be to use:

<a4j:support event="onRowDblClick" requestDelay="400" actionListener="#{channelsBean.editDataItem}" ajaxSingle="true">

     <f:param name="row" value="#{channelAttr.somePropToIdentifyTheObjectEGId}"

</a4j:support>

andd remove binsing - as putting UIComponent to session - will be the cause of much problems in JSF.

Hi,

I could not achieve this functionality using dataTable so I had to migrate my code to rich:extendedDataTable and this provides the selection of rows also.
