Question

I want to know how to update a PrimeFaces Datatable rows. This is my datatable photo to understand me well:

I want to choose for each row his respective state and then click Save States button to save these values.

This is my xhtml page code:

<p:panel header="List Of Players For: #gameMB.selectedGame.teamCompetitionByGuestTeam}">
  <p:dataTable var="gam" value="#{gamePlayerMB.listGamePlayerGuest}">
    <p:column headerText="Name Lastname">
        <h:outputText value="#{gam.playerName}/>
    </p:column>
    <p:column>                                      
     <p:selectOneRadio value="#{gam.state}">
        <f:selectItem itemLabel="Titulaire" itemValue="Titulaire" />
        <f:selectItem itemLabel="Remplaçant" itemValue="Remplaçant" />
        <f:selectItem itemLabel="Blesse" itemValue="Blesse" />
        <f:selectItem itemLabel="Non retenu" itemValue="Non retenu" />
     </p:selectOneRadio>
    </p:column>
 </p:dataTable>
 <f:facet name="footer">
<p:commandButton value="Save States"
    action="#{gamePlayerMB.testRadioGuest}" />
</f:facet>
</p:panel>

Thanks in advance.

Answer 1

1. You should have used simple h:outputText as a component to render the Player's state (Titulare,Blessé,...)
2. Use primefaces datatable editable="true" with p:selectOneMenu in the p:cellEditor to render the list of available choices.

Answer 2

If I've understood you right, You just want to create table with edit function. For solving this trouble just pass your table and your button to form.

<h:form>
   <p:dataTable var="gam" value="#{gamePlayerMB.listGamePlayerGuest}">
      ...
   </p:dataTable>
   <p:commandButton value="Save States" action="#{gamePlayerMB.testRadioGuest}" />
</h:form>

In this case on Save-button click all form will be sent to the server (with all your changing). Your testRadioGuest method may looked like this

private void testRadioGuest(){
   for(Player player: listGamePlayerGuest){
      System.out.println(player);
   }
}

All state changing must be saved.
