    random IllegalArgumentExcpetion with selectItems - convertEntity

    Evan Scharfer Newbie

      I get an illegalArgumentException with my selectItems / convertEntity about 5% of the time when submitting the drop down box. I do not know how to reproduce it consistently. It can happen anytime during your session. I am using seam 2.1, jdk 1.5, and jboss 5. Below is the xhtml and the component that fills the skus list. Could someone please try to help? It is a very annoying problem and I can't figure out the cause.



      <div class="productinfo">            
                                      
                                      <h2>#{currentProduct.shortDescription}</h2>                        
                                      <div class="description">
                                              <h:outputText value="#{currentProduct.longDescription}" />
                                      </div>
                                      <br/>
                                      <h:selectOneMenu id="selectSku" value="#{shoppingCart.newSku}">
                                        <s:selectItems value="#{skus}" var="sku" label="#{skuAction.getFormattedSkuPrice(sku)} : #{sku.skuCode}"/>
                                                                 <s:convertEntity /> 
                                                              </h:selectOneMenu>                                
                                      Qty: <h:inputText size="3" value="#{shoppingCart.newQuantity}"/>
                                  
                              </div>

              skus = currentProduct.getSkuList();
          }
          
      



      And the exception:
