我正在尝试为其添加一个全局过滤器,我<p:dataTable>
从托管 bean 以编程方式创建该过滤器。该表工作正常并且可以正确呈现,但是只有最后添加的组件会在datatable
构面中呈现。这是我尝试过的代码:
//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);
globalfilterinput.setId("globalFilter");
ValueExpression globalfilterJSaction = ef.createValueExpression(elc, "examTable.filter()", Object.class);
globalfilterinput.setValueExpression("onkeyup", globalfilterJSaction);
Map comps = new HashMap();
comps.put("header", tableTitle);
comps.put("header", globalfilterinput);
table.getFacets().putAll(comps);

Column indexColumn = (Column) application.createComponent(Column.COMPONENT_TYPE);
UIOutput indexColumnTitle = (UIOutput) application.createComponent(UIOutput.COMPONENT_TYPE);
indexColumnTitle.setValue("Index");

//table.getColumns().add(column);
table.getChildren().add(indexColumn);
