PrimeFaces Dropdown AutoComplete inside composite component

Question

I'm trying to embed the primefaces autocomplete method inside a composite component.

However, it fails when trying to access the "complete" method.

Here is my code:

..
<composite:interface>
  <composite:attribute name="car" required="true" />
  <composite:attribute name="brandList" required="true" method-signature="java.util.List complete(java.lang.String)" />
  <composite:attribute name="style" required="false" />
</composite:interface>

<composite:implementation>
  ..

  <h:outputLabel value="DropDown :" for="dd" />
  <p:autoComplete id="dd" dropdown="true" value="#{cc.attrs.car.brand}" completeMethod="#{cc.attrs.brandList}" />
  ..
</composite:implementation>

And the call:

<cp:carPropertiesAutoComplete car="#{carController.car}" brandList="#carController.complete}" />

And the backing bean:

public List<String> complete(String query) {
  List<String> brandList = new ArrayList<String>();

  brandList.add("brand0");
  brandList.add("brand1");

  for (String brand : brandList) {
    if(brand.contains(query)) {
      brandList.add(brand);
    }
  }
  return brandList;
}

And the log:

I have googled around and found this (same problem with no solution) http://forum.primefaces.org/viewtopic.php?f=3&t=1884

I am running Glassfish server 3.1.2 with Mojarra 2.1.6 and PrimeFaces 3.3.1

Can you please help me? I have struggled with this for hours =(

Why you dont create your complete method in a @FacesComponent? and then use {cc.brandList} not {cc.attrs.brandList}
