    copied!<p>I got a problem using selectOneMenu, it can clearly convert the Suppliers to SupplierBean (my boss use to call it that way-he was the one who set it up), and display it correctly on the page, but the moment i save it, it returns a null value.</p> <p>My code in XHTML:</p> <pre><code> &lt;p:selectOneMenu value="#{itemSupplierController.supplierBean}" converter="supplierConverter"&gt; &lt;f:selectItem itemLabel="Select..." itemValue="" /&gt; &lt;f:selectItems value="#{supplierController.suppliersBean}" var="s" itemValue="#{s}" itemLabel="#{s.supplierName}" /&gt; &lt;/p:selectOneMenu&gt; </code></pre> <p>Code in SupplierBean:</p> <pre><code>public class SupplierBean { private int id; private String supplierName; public SupplierBean(){ } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getSupplierName() { return supplierName; } public void setSupplierName(String supplierName) { this.supplierName = supplierName; } } </code></pre> <p>Code for converter:</p> <pre><code>@FacesConverter(value = "supplierConverter") public class SupplierConverter implements Converter { private static final Logger logger = Logger.getLogger("SupplierConverter"); @Override public Object getAsObject(FacesContext arg0, UIComponent arg1, String id) { logger.info(id); SupplierManager manager = EjbInitializer.getSupplierManager(); if (StringUtils.isNullOrEmpty(id) || !org.apache.commons.lang.math.NumberUtils.isNumber(id)) { return null; } else { SupplierBean sb = null; try { sb = convertToPojo((Supplier) manager.find(Integer.valueOf(id))); } catch (SoftTechPersistenceException e) { e.printStackTrace(); } return sb; } } @Override public String getAsString(FacesContext arg0, UIComponent arg1, Object s) { String val = null; logger.info("object: " + s); if (s != null &amp;&amp; (s instanceof SupplierBean)) { SupplierBean supplier = (SupplierBean) s; val = Integer.toString(supplier.getId()); } logger.info(String.format("value %s", val)); return val; } public static SupplierBean convertToPojo(Supplier s) { SupplierBean supplier = new SupplierBean(); supplier.setId(s.getId()); String name = ""; if (s.getFullName().isEmpty()) { name = s.getFullName(); } else { name = s.getCompany(); } supplier.setSupplierName(name); return supplier; } } </code></pre> <p>Overview of the methods in my backingBean that i use to save the supplier(I used to call it controller):</p> <pre><code>public void supplierSave() { logger.info("supplier save or update commenced."); if (SupplierAction.Create.equals(supplierCurrentAction)) { logger.info("adding supplier to the table..."); addSupplierToTable(); } else if (SupplierAction.Update.equals(supplierCurrentAction)) { logger.info("supplier updating..."); updateSupplier(); } } public void addSupplierToTable() { try { logger.info(String.format("supplier id: %s", getSupplierBean().getId())); setSupplier((Supplier)supplierManager.find(getSupplierBean().getId())); getItemSupplier().setSupplier(getSupplier()); getItemSuppliers().add(getItemSupplier()); resetSupplier(); } catch (Exception e) { e.printStackTrace(); } logger.info("supplier successfully added to the table."); } </code></pre>
