[Chelis Flores]

Hi all
I new in JSF, I want to know how to do to obtain the row was selected in a datatable, I show a List in the datatable, in the datatable there are several columns and commandlink, in this, I send another action, but how can I do for obtain the row was selected
this is my code,thanks, and sorry for the writting I know english a little bit.

<h:column>
<f:facet name="header">
<h:outputText styleClass="tablaitem" value="EMISORA"></h:outputText>
</f:facet>
<h:commandLink target="_blank" id="emisora" action="#liquidacionPorDecretosHandler.consultarListaDecretosDetalle}">
<h:outputText value="#decretos.emisora}">
</h:outputText>
</h:commandLink>
</h:column>

in the <h:dataTable> tag, you should have defined an attribut "var". The bean associated with the selected row is stored in the request with this name.

In my case, the name is " varrecords", thus I get the bean with

this.getRequestScope.get("varrecords")

hope this helps!

The DataTable control required a model data wrapper, so if you write an action processor, you can query the data wrapper:

    private DataModel list;
 
    private void loadProjectList() {
        final Vector lst0 = MyDao.getStuff();
 
        list = new ListDataModel();
        list.setWrappedData(lst0);
    }
 
    /**
     * This method caches the selected list row,
     * and the JSF navigator then takes me to a detail
     * page which allows me to edit it.
     */
    public String consultarListaDecretosDetalle() {
        this.editItem = 
            (Stuff) list.getRowData());
        return "success";
    }

I like to end the names of my action processors with "Action" so that it's more obvious that they're actions and not properties. JSF doesn't care, but it makes my life simpler.
