Binding HtmlGmap java.lang.IllegalArgumentException: argument type mismatch

[derkd]

Hi all,

I have a weird binding problem. I want to bind an HtmlGmap component to my backing bean.
My page code looks like this:

<rich:panel>
                   <rich:gmap 
                        binding="#{googleMapsBinding.map}"
                         mapType="G_NORMAL_MAP"
                         
                         gmapVar="_map"
                         
                         gmapKey="ABQIAAAAbHnR2PtFer2KlA48Z0skqBT2yXp_ZAY8_ufC3CFXhHIE1NvwkxTDRxKRsg12uu50ETM4gFqD5UPusA"
                         oninit="drawDistrict(_map)" 
                         id="map">
               
                    </rich:gmap>
              </rich:panel>

I bind it to an event scope component:

@Name("googleMapsBinding")
@Scope(ScopeType.EVENT)
public class GoogleMapsBinding implements Serializable {

     private static final long serialVersionUID = 6073074679639877962L;
     /**
      * This class is in EVENT scope 
      * and injected in the MapsAction which is in conversation scope. 
      * You can't bind a conversational class. On a postback request, 
      * component bindings are updated during the Restore View phase, 
      * before the Seam conversation context has been restored.
      * 
      */
     
     private HtmlGmap map;
     
     public HtmlGmap getMap() {
          return map;
     }
     
     public void setMap(HtmlGmap map) {
          this.map = map;
     }

     

}

This component is injected into my MapAction which is in conversation scope.

When I load my page I get an:

12:07:38,531 ERROR [viewhandler] Error Rendering View[/mapAdmin.xhtml]
javax.faces.FacesException: javax.el.ELException: /mapAdmin.xhtml @116,15 binding="#{googleMapsBinding.map}": java.lang.IllegalArgumentException: argument type mismatch

What am I doing wrong?
