Confirmation on BrowseBean.clickSpace method

Question

Hi All,
I am working on customizing an Alfresco page browse.jsp. And i have been finding it very difficult to pass parameters from the jsp to my Backing bean.After analysing a few f:param tags in the browse.jsp page i stumbled upon line no 271
<a:actionLink id="col1-act1" value="#{r.name}" image="/images/icons/#{r.smallIcon}.gif" actionListener="#{BrowseBean.clickSpace}" showLink="false">
<f:param name="id" value="#{r.id}" />
</a:actionLink>The actionListener 'BrowseBean.clickSpace' inside BrowseBean.java is
public void clickSpace(ActionEvent event)
      UIActionLink link = (UIActionLink)event.getComponent();
      Map<String, String> params = link.getParameterMap();
      String id = params.get("id");
      if (id != null && id.length() != 0)
         try
              System.out.println("ClickSpace event called");
            NodeRef ref = new NodeRef(Repository.getStoreRef(), id);
            // handle special folder link node case
            if (ApplicationModel.TYPE_FOLDERLINK.equals(this.getNodeService().getType(ref)))
               ref = (NodeRef)this.getNodeService().getProperty(ref, ContentModel.PROP_LINK_DESTINATION);
            clickSpace(ref);
         catch (InvalidNodeRefException refErr)
            Utils.addErrorMessage(MessageFormat.format(Application.getMessage(
               FacesContext.getCurrentInstance(), Repository.ERROR_NODEREF), new Object[] {id}) );
   }The inference i have drawn from the above two code sources is that
1)Considering the JSP code, i assume that the id parameter passed using f:param is 'one id for every content'.Almost like a collection of id's
2) The actionListener BrowseBean.clickSpace is called for every id of the content .So if i had an arrayList to capture all the id's from inside the clickSpace actionListener i will be successfull in doing that.
3)I will be able to pass the parameter like r.name in the place of r.id.
Just need a confirmation on whether my assumptions are true.I have tried customizing the page using these inferences but have failed.Thank You.

Answer 1

you are definitely right
here is my code which works fine
page:
<h:commandLink action="doRefresh" actionListener="#{AdminBatchesBean.doSort}">
    <h:outputText id="selectBatchColumn" value=" ">
        <f:param value="rows"/>
        <f:param value="selected"/>
    </h:outputText>
</h:commandLink>bean:
public void doSort(ActionEvent event) {
    final UIComponent out = (UIComponent) event.getComponent().getChildren().get(0);
    UIParameter param = (UIParameter) out.getChildren().get(0);
    final String listName = (String) param.getValue();
    param = (UIParameter) out.getChildren().get(1);
    final String fieldName = (String) param.getValue();
    blah-blah-blah
}
