Hi Gerard, Thanks for you pointer to the wiki. I must have overlooked the documentation in wiki, because indeed with that information I will be able to get it working.
With kind regards, Marco -----Original Message----- From: Gerald Müllan [mailto:[EMAIL PROTECTED] Sent: woensdag 17 januari 2007 13:57 To: MyFaces Discussion Subject: Re: How to use inputSuggest(Ajax) Hi, you can find any information about inputSuggestAjax on the corresponding wiki site: http://wiki.apache.org/myfaces/InputSuggestAjax You should use this component if you need something like autoSuggest functionality. The typed string into the input is passed to the suggestedItems method. It was designed to give the user a dynamically retrieved list of suggested Strings back. If you need something like the selectItems approach, it is not the right choice for you. cheers, Gerald On 1/16/07, Beelen, Marco <[EMAIL PROTECTED]> wrote: > > > > Hello, > > I would like to use some inputSuggest functionality in my application, but > can't get the inputSuggest or inputSuggestAjax component working properly. > > What I can't appair to get correct is return types on the methods on my > managed-bean which provided the available options and the handling of a > submitted value. > > In my application I have a class Product with an id and a name and my DAO > provides me with a List<Product>. > > Prior to my attempts to use inputSuggest I was using: > > <h:selectOneMenu value="#{managedBean.selectedProductId}"> > <t:selectItems > value="#{managedBean.products}" > var="product" > itemLabel="#{product.name}" > itemValue="#{p.id}" > /> > </h:selectOneMenu> > > And during the handling of the form I would lookup the proper Product by > it's id. > > My assumption was that <s:inputSuggest> also could work with <t:selectItems> > so I wrote the xhtml like this: > <s:inputSuggest value="#{managedBean.name}" required="true"> > <t:selectItems > value="#{managedBean.products}" > var="product" > itemLabel="#{product.description}" > itemValue="#{product.description}" > /> > </s:inputSuggest> > > But that causes a ClassCastException during rendering. > > java.lang.ClassCastException: [Ljavax.faces.model.SelectItem; > at > org.apache.myfaces.custom.suggest.InputSuggestRenderer.getChoices(InputSuggestRenderer.java:224) > at > org.apache.myfaces.custom.suggest.InputSuggestRenderer.encodeBegin(InputSuggestRenderer.java:100) > at > javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:512) > at > com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:232) > at .. > > So I switched to: > > <s:inputSuggest value="#{mangedBean.name}" required="true"> > <f:selectItems value="#{managedBean.productSuggests}"/> > </s:inputSuggest> > > Where the managedBean.getProductSuggests() returns a Map<String, String> > Now the page get rendered and I can enter a product name with suggestion. > ( Although with some style issues with the suggestions being underneath > other form elements, but that a minor issue for later. ) > > In method called by the action of my commandButton on the from I would like > to get the appropreate Product-object, so I wanted to perform a lookup based > upon the field name of the managedBean.
