    Binding HtmlGmap java.lang.IllegalArgumentException: argument type mismatch

    Derk Dukker Novice

      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?
