    a4j action param - am I using it correctly?

    Chris Simons Expert

      All,

      I'm attempting to assign a value to a manager/session bean (not an entity bean) using a4j:actionParam. From reading the instructions on the RichFaces demo site, I got the impression this could be done. However, whenever I click on the a4j:commandLink with the embedded actionParam, I'm getting an exception that the assignTo value is not a valid property. The property does have getters/setters.

      Code is below then followed by the exception. Please give me your thoughts when you have a moment - thanks.


      Code

      <a4j:commandLink value="Add User"
      action="#{userPicker.initPicker('eventManager.addContact', contactTypes.id)}"
      onclick="#{rich:component('defaultUserPickerModal')}.show()">
      <a4j:actionparam name="selectedContactTypeId" value="#{contactTypes.id}"
      assignTo="#{eventManager.selectedContactTypeId}"/>
      </a4j:commandLink>


      From Session bean:
      In(required = false, scope = ScopeType.CONVERSATION)
       @Out(required = false, scope = ScopeType.CONVERSATION)
       private String selectedContactTypeId = "";
      
       public String getSelectedContactTypeId() {
       return selectedContactTypeId;
       }
      
      
       public void setSelectedContactTypeId(String selectedContactTypeId) {
       this.selectedContactTypeId = selectedContactTypeId;
       }
