Component annontation and For component

Hi I am trying to replace my .page file with annotations
but when I am using the @Component with a For Component I got an Exception.

this is my annotated code:

    @Persist
    public abstract Product getCurrentProduct();
    public abstract void setCurrentProduct(Product product);

    @Component(id="products", type="For", bindings= {"source=Products",
"value=currentProduct", "element=tr"})
    public Iterator getProducts() {
        return Catalog.getGlobalCatalog().getProducts().iterator();
    }

and this is my working .page file snipped:

    <property name="currentProduct"/>
    <component id="products" type="For">
        <binding name="source" value="ognl:products"/>
        <binding name="value" value="currentProduct"/>
        <binding name="element" value="literal:tr"/>
    </component>

And this is the exception i get when using the annotated code:
org.apache.hivemind.ApplicationRuntimeException  Component Home/products is
not assignable to type java.util.Iterator.  location: Annotation @
org.apache.tapestry.annotations.Component(inheritInformalParameters=false,
bindings=[source=Products, value=currentProduct, element=tr], id=products,
type=For) of public java.util.Iterator
org.comptour.tapestry.Home.getProducts()  Stack Trace:

   - org.apache.tapestry.TapestryUtils.getComponent(TapestryUtils.java:304)

   - $Home_28.finishLoad($Home_28.java)
   - org.apache.tapestry.pageload.PageLoader.constructComponent(
   PageLoader.java:439)
   - org.apache.tapestry.pageload.PageLoader.loadPage(PageLoader.java:613)


....

what could be the Issue??

Thanx
Rolf

Sorry to bother you all (again ;-))
I should have created an abstract method that returned the Form component.
and should not have anotated the the source of the component.
