Error when deselecting data from a table

  • 772

Good morning,

This is my code:

public void seleccionarTodos(AjaxBehaviorEvent event){
   if(isIsSelectedAll()==true){        

        this.selectedFuentes=fuente;
        setIsSelectedAll(false);

    }else{
            this.selectedFuentes.clear();
            setIsSelectedAll(false);
      }
}

I have a table with a general checkbox that when pressed will select all the data that the table contains (the table contains a page)

then when I do the first search, it shows me the data (the data appears selected by default)

enter image description here

when I click the general checkbox it works fine, but if I leave the data deselected and perform another search, it will show the data selected by default but when I click the checkbox to deselect them, something very strange happens (the data is deselected and again select) and I don't know what to do.

This is the code of the table:

    <p:dataTable  id="datos" var="f"  rowKey="#{f.num}"
              resizableColumns="true" value="#{busquedaBean1.fuente}"
             selection="#{busquedaBean1.selectedFuentes}" style="margin-bottom:0;margin-top: 0%;"  
             rows="11" paginator="true"  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:ajax event="toggleSelect" global="true" update="datos"  listener="#{busquedaBean1.seleccionarTodos}"   />

    <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="true"   >

    </p:column>
</p:dataTable>

  1. You need the rowUnselectCheckboxand you can also include the rowSelectCheckbox 

    <p:ajax event="rowSelect"   listener="#{busquedaBean1.selectedFuentes}"/>
<p:ajax event="rowUnselect" listener="#{busquedaBean1.selectedFuentes}"/>
<p:ajax event="rowSelectCheckbox"   listener="#{busquedaBean1.selectedFuentes}"/>
<p:ajax event="rowUnselectCheckbox" listener="#{busquedaBean1.selectedFuentes}"/>

    I already found the solution and what happened was that the value is not reset so I reset it every time I was going to perform a search in this way, the only thing I did was add this: isSelectedAll = false;and that's it, problem solved.
