Method not found EL expression throwing error?

[samuraicoder]

In this code is a call to the customerSession.setSelectedAddress(null) method...
This is so we can add a new shipping address even if we already have one.

                                                        <s:link styleClass="add_address_link"
                                                                action="#{customerSession.copyAddress}" value="Add New Address">
                                                                <a:support event="onclick"
                                                                        actionListener="#{customerSession.setSelectedAddress(null)}"
                                                                        reRender="shipInputAjax, ship01shipmentMethodCodeAdjx, cartViewAjax"
                                                                        ajaxSingle="false" />
                                                        </s:link>  

On the backend is:

        /**
         * @return the selectedAddress
         */
        public CustomerShipmentAddress getSelectedAddress() {
                return selectedAddress;
        }

        public void setSelectedAddress(CustomerShipmentAddress selectedAddress) {
                this.selectedAddress = selectedAddress;
        }       

I am getting a warning on the front end code, saying setSelectedAddress cannot be resolved.

What does that mean and how can I fix it please. We are using SEAM and this is a SESSION backing bean.

Thanks much,

p.s. JBOSS developer studio classifies it as Type Validation Message problem.

In case someone drop here like i do actionListener="#{customerSession.setSelectedAddress(null)}"  is a listener and not a direct action in listner you must implement ActionEventListener method

1. public void setSelectedAddress(ActionEvent event) { 
2.         }
