    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:


      I bind it to an event scope component:

      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?
