How to select all data from a table in java?

  • 772

Good morning,

I need to select all the data from a table (it has pagination).

Code:

  <p:dataTable  id="datos"
              var="f" 
              rowKey="#{f.num}"
              resizableColumns="true" 
              value="#{busquedaBean1.fuente}"
              selection="#{busquedaBean1.selectedFuentes}"
              style="margin-bottom:0;margin-top: 0%;"  
              paginatorTemplate="{CurrentPageReport} 
             {FirstPageLink} {PreviousPageLink}
             {PageLinks} {NextPageLink} {LastPageLink}" >

    <!-- CONTENIDO DE LA TABLA -->
    <p:ajax event="rowSelect" global="true"  listener="#{busquedaBean1.selectedFuentes}"   />
    <p:ajax event="rowUnselect" global="true"  listener="#{busquedaBean1.selectedFuentes}"   />

    <p:column headerText="Nombre" style="width:80%;" sortBy="#{f.nombre}">
        <h:outputText value="#{f.nombre}" />
    </p:column>

    <p:column headerText="Fecha" style="width:108%;" sortBy="#{f.fecha}" >
        <h:outputText value="#{f.fecha}" />
    </p:column>

    <p:column headerText="Bloqueo" width="65" sortBy="#{f.bloqueo}">
        <h:outputLabel value="#{f.bloqueo}" rendered="#{empty f.fechaBloqueo}" style="padding: 0 20%;"/>                                       
        <p:commandButton value="#{f.bloqueo}" rendered="#{ not empty f.fechaBloqueo}" id="detBloqueo" update=":form:carDetail" oncomplete="PF('carDialog').show()" icon="ui-icon-search" title="Mostrar detalles" style="background: transparent;  color:#4297d7;border: 0px;" styleClass="detalles">
            <f:setPropertyActionListener value="#{f}" target="#{busquedaBean1.autor}" />
        </p:commandButton>
    </p:column>


    <p:column width="16" >
        <h:commandLink title="Descargar" target="_blank"  actionListener="#{descargarFormaBean.descargar(f.forma,f.nombre)}">
            <span class="ui-button-icon-left ui-icon ui-icon-arrowthickstop-1-s" style="text-align:center;"></span>
        </h:commandLink>
    </p:column>

    <p:column headerText="Directorio" width="190" sortBy="#{f.directorio}">
        <p:commandButton value="#{f.dir}"  id="detDirectorio" update=":form:dirDetail" oncomplete="PF('dirDialog').show()" title="Mostrar detalles" style="background: transparent;  color:black;border: 0px;" styleClass="detalles">
            <f:setPropertyActionListener value="#{f}" target="#{busquedaBean1.autor}" />
        </p:commandButton>
    </p:column>

    <p:column  id="SelectFuentes"   style="width:16%;text-align:center" selectionMode="multiple" exportable="false"   >

    </p:column>



</p:dataTable>

When selecting the CheckBox of the column to select all the data, it does not select the other pages, it only selects the page that is active (the one that the user is seeing), and I need it to select everything.

NOTE: I was investigating and it says that it is a bug in the version of primefaces 5.1 but I'm not sure.

Thank you so much.

    I already found the solution:

    Code:

    <p:ajax event="toggleSelect" global="true" update="@form"  listener="#{busquedaBean1.seleccionarTodos}"   />

    We have to create that ajax method, then we go to our Bean.java (in my case it is busquedaBean1and we call the java method:

    Code:

    /**
 * @return the isSelectedAll
 */
public boolean isIsSelectedAll() {
    return isSelectedAll;
}

/**
 * @param isSelectedAll the isSelectedAll to set
 */
public void setIsSelectedAll(boolean isSelectedAll) {
    this.isSelectedAll = isSelectedAll;
}



  public void seleccionarTodos(AjaxBehaviorEvent event){
    if(isIsSelectedAll()==false){
        this.selectedFuentes=fuente;
        setIsSelectedAll(true);
    }else{
        this.selectedFuentes.clear();
        setIsSelectedAll(false);
    }
}


Y listo problema resuelto, espero que les sirva a todo.
