Re: dataTable and commandButton question

[Grigoras Cristinel]

Hi,
In myfaces examples is an example about using x:updateActionListener, in 
dataTable.jsp,
you can set any property you want.
Is working for me.

       <h:column>
                      <f::facet name="header">
                         <h:outputText 
value="#{example_messages['label_country_name']}" />
                      </f::facet>
                      <x:commandLink action="go_country" immediate="true" >
                           <h:outputText value="#{country.name}" />
                           <!-- for convenience: MyFaces extension. 
sets id of current row in countryForm -->
                           <!-- you don't have to implement a custom 
action! -->
                           <x:updateActionListener 
property="#{countryForm.id}" value="#{country.id}" />
                      </x:commandLink>
                  </h:column>

There are a few ways to do this.  The easiest is to get call:
FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("var");
where "var" is the name of your datatable's variable.

    I have a dataTable with a commandButton rendered on
    each row.  When the commandButton is pressed I need
    it's managed bean method to know which row the button
    was pressed for.  So how can the method know which row
    to process?
    Thanks,
    Ray
