RichFaces 4 autocomplete is not showing suggestions

问题

I am trying for too long to make an autocomplete custom suggestion demo. The demo is partially working as I can see the suggestions response in f12 debugger, but it is not showing in the drop down box. I am doing the following

POM:

 <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <org.richfaces.version>4.3.3.Final</org.richfaces.version>

</properties>

<repositories>
    <repository>
        <id>org.openfaces</id>
        <url>http://repository.openfaces.org/repository</url>
    </repository>
    <repository>
        <id>jfree</id>
        <url>http://www.ibiblio.org/maven/jfree/</url>
    </repository>
</repositories>

<dependencies>
    <dependency>
        <groupId>org.richfaces</groupId>
        <artifactId>richfaces-bom</artifactId>
        <version>${org.richfaces.version}</version>
        <scope>import</scope>
        <type>pom</type>
    </dependency>
    <dependency>

        <artifactId>richfaces-core-impl</artifactId>
        <version>${org.richfaces.version}</version>
    </dependency>

the bean:

    @ManagedBean    
    @RequestScoped
    public class TagCollector  implements Serializable{

    private static final long serialVersionUID = 4930140495481611695L;
    String tagName;
    public Converter getTagNameConverter(){
        return new Converter() {

            @Override
            public String getAsString(FacesContext context, UIComponent converter, Object value) {
                System.out.println("getAsString=" +(String)value);
                return (String)value;
            }

            @Override
            public Object getAsObject(FacesContext context, UIComponent converter, String value) {
                System.out.println("getAsObject=" +value);
                return value;
            }
        };
    }

    public List<String> getSuggestedTags(){
        String searchString = Faces.var("searchString", String.class);
        System.out.println("getSuggestedTags searchString="+ searchString);
        List<String> suggestedTags = Arrays.asList(new String[]{"ford", "mazda", "fiat"});
        return suggestedTags;   
    }

    public String getTagName() {
        return tagName;
    }

    public void setTagName(String tagName) {
        this.tagName = tagName;
    }
   }

the xhtml:

    <h:form>
        <h:outputText value="Enter state" />
        <rich:autocomplete mode="ajax" minChars="1" showButton="true"
            autocompleteMethod="#{userBean.autocomplete}">
</rich:autocomplete>
    </h:form>

the faces config:

<managed-bean>
    <managed-bean-name>tagCollector</managed-bean-name>
    <managed-bean-class>org.taagad.tag.model.TagCollector</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope> 
</managed-bean>

I really search the web for hours getting nowhere, any idea will be helpful.

I solved this issue! it is working on jsf 2.1.25. Same issue was with RichFaces, it appears both implementations are sensitive to the same issue/bug with jsf iml and api. That's the pom on my project:

    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <version>2.1.25</version>
    </dependency>
    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-impl</artifactId>
        <version>2.1.25</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
    </dependency>
    <dependency>
        <groupId>javax.portlet</groupId>
        <artifactId>portlet-api</artifactId>
        <version>2.0</version>
        <scope>provided</scope>
    </dependency>
