Re: set UIParameter in backing bean

[Emily Gu]

I know you can get it as following. I don't know whether you have another way to do it though.

 

  public void actionListener (ActionEvent event) {
     FacesContext context = FacesContext.getCurrentInstance();
     param = (String)context.getExternalContext().getRequestParameterMap().get("bluh");
     System.out.println("param: " + param);
     setParam("bluh2");
   }

 

You can have regular setter and getter for param in the backing bean.

Hello,

 

I've got a JSF application which uses the <f:param> tag embedded in a <h:commandLink> tag in several places. Now I need to set a parameter in a backing bean that is accessible to the JSP when the page is re-rendered (the same page is reloaded after the actionlistener executes, no navigation taking place).

 

How would I go about attaching a parameter so that it would be accessible? Note that this type of code doesn't work:

 

Public void actionListener (ActionEvent evt)

{

            UIParameter uip = new UIParameter();

            Uip.setName("blah");

            Uip.setValue("blah");

            Uip.setParent(Evt.getComponent());

}

 

I am guessing this is because the component tree is re-created when the response is rendered, and that therefore the parameter disappears when my JSP tries to get to it.

 

Any ideas as to how this would be done? I'm pretty lost and would appreciate your help.
