Binding primefaces dataTable with org.primefaces.component.datatable.DataTable;
Solution 1
java.lang.String cannot be cast to javax.faces.component.UIComponent.
The binding
attribute must refer an UIComponent
, not a plain vanilla String
. And indeed, you forgot the #{}
around the attribute value which would make it to be treated as a plain vanilla String
.
Fix it accordingly:
binding="#{saProductCategoryController.dtProductCategory}"
Solution 2
Replace
binding="saProductCategoryController.dtProductCategory"
with
binding="#{saProductCategoryController.dtProductCategory}"

I have a question regarding primefaces datatable component. I want to bind a DataTable variable to the p:dataTable so that I would be able to manipulate the first, rows, rowsPerPageTemplate, etc. programmatically from the backing bean. But I'm stuck and keep getting java.lang.String cannot be cast to javax.faces.component.UIComponent.
Here's my p:dataTable declaration.
<p:dataTable id="dtProductCategoryList" value="#{saProductCategoryController.saproductcategories}" rowsPerPageTemplate="#{appConfig.rowsPerPageTemplate}" paginatorTemplate="{RowsPerPageDropdown} {FirstPageLink} {PreviousPageLink} {CurrentPageReport} {NextPageLink} {LastPageLink}" currentPageReportTemplate="{currentPage} #{bundle.DataTablePageSeparator} {totalPages}" paginatorAlwaysVisible="false" var="item" paginator="true" rows="#{appConfig.rowsPerPageDefault}" binding="saProductCategoryController.dtProductCategory">
And here's my ViewScoped backing bean.
private DataTable dtProductCategory; /** Creates a new instance of saProductCategoryController */ public SaProductCategoryController() { } @PostConstruct public void Init() { try { dtProductCategory = new DataTable(); //dtProductCategory. saproductcategories = saProductCategoryFacade.selectAll(); LogController.log.info("Creating postconstruct for saProductCategoryController"); } catch (Exception ex) { LogController.log.fatal(ex.toString()); } }
What could be the problem? It seems that the DataTable variable is mistaken for a String?
Appreciate all your help. Thanks.
