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 ..
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. Only the value of
that field wasn't the exact value of the suggestion but something like
"m:_id100_choicePRODUCTNAME"
I don't know where the prefix 'm:_id100_choice" comes from, but I don't
suppose mu managedBean should be responsible for stripping it.
Is this a bug or am I doing something wrong?
As an alternative I was looking at <s:inputSuggestAjax> so I changed the
xhtml to:
<s:inputSuggestAjax
suggestedItemsMethod="#{managedBean.productSuggests}"
value="#{mangedBean.name}" charset="utf-8" />
I tried to implement productSuggests-method with returning: Map<String,
String>, List<String>, List<SelectItem>, but nothing worked.
In all cases the page does get rendered, but no inputSuggest is
available due to JavaScript-errors. ('Can't "move focus to the control
because it is invisible, not enalbed or of a type that doesn't accept
focus")
Any (input)suggestion on how to work with these components is greatly
appreciated.
With kind regards,
Marco Beelen
