Body
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. <pre><code><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"> </code></pre> And here's my ViewScoped backing bean. <pre><code> 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()); } } </code></pre> What could be the problem? It seems that the DataTable variable is mistaken for a String? Appreciate all your help. Thanks.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
