Ich versuche, einen globalen Filter für meine hinzuzufügen<p:dataTable> Davon erstelle ich programmgesteuert aus einer verwalteten Bean. Die Tabelle funktioniert einwandfrei und wird korrekt gerendert, es wird jedoch nur die zuletzt hinzugefügte Komponente im gerendertdatatable Facette. Hier ist der Code, den ich ausprobiert habe:

    //config
    FacesContext fc = FacesContext.getCurrentInstance();
    Application application = fc.getApplication();
    ExpressionFactory ef = application.getExpressionFactory();
    ELContext elc = fc.getELContext();

    //Table
    table = (DataTable) application.createComponent(DataTable.COMPONENT_TYPE);
    table.setId("tabexam");
    table.setValue(listexam);
    table.setVar("exam");
    table.setWidgetVar("examTable");
    table.setEmptyMessage("aucun résultat trouvé pour votre recherche");
    table.setFilteredValue(filteredexams);
    table.setPaginator(true);
    table.setPaginatorPosition("bottom");
    table.setRows(25);
    table.setPaginatorTemplate("{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}");
    table.setRowsPerPageTemplate("10,25,50,100");


    /////////this is the part that regards this question///////////
    /*
     this is the HTML code that i want to translate to java code :
     <f:facet name="header" >  
     <h:outputText value="Rechercher:  "/>  
     <p:inputText id="globalFilter" onkeyup="examTable.filter();" style="width:200px" /> 
     </f:facet>

    UIOutput tableTitle = (UIOutput) application.createComponent(UIOutput.COMPONENT_TYPE);

    tableTitle.setValue("Rechercher :");

    HtmlInputText globalfilterinput = (HtmlInputText) application.createComponent(HtmlInputText.COMPONENT_TYPE);
