RequestParameter issue null value

[salski22]

I'm having problem with RequestParameter passing

<h:outputFormat value="#{SetW.who3}">
   <f:param name="pary" value="some string"/>
</h:outputFormat>

my bean

@Name("SetW")
public class SetWhos {
     
      private String who3;

      @RequestParameter("pary")
      private String pary;
      
      public String getWho3() 
      {
          System.out.println("c1_" + pary);
          who3 = "My parameter" + pary;
      }     
     
      return who3;
}

the pary variable from xhtnl is not passed to the bean, it is always null.

Anybody knows why?

Does it true that f:param works on h:commandLink and h:outputLink only. If so, how can I pass parameter to backing bean from xhtml outputtext?
I have three values that I can display in outputtext using

<h:outputFormat value="{0}{1}{2}{3}">
         <f:param value="#{event.single}"/>
         <f:param value="#{event.couple}"/>
         <f:param value="#{event.children}"/>
         <f:param value="#{event.groups}"/>
</h:outputFormat>

but I need to format those 3 values in one string with some additional text depending on these vales. So how can I use bean from above to format outputtext

I found solution :) Maybe this post will be helpfull for someone

We need outputtext

<h:outputText binding="#{SetW.text}" value="#{SetW.textValue}" >
         <f:attribute name="attributename" value="#{event.city}" />
     <f:attribute name="attributename1" value="#{event.eventname}" />
</h:outputText>

and backing bean

@Name("SetW")
public class SetWhos {

     private HtmlOutputText text;

     public HtmlOutputText getText() {
          return text;
     }

   public String getTextValue() {
        return (String) text.getAttributes().get("attributename") +
        (String) text.getAttributes().get("attributename1");
    }
     
     public void setText(HtmlOutputText text) {
          this.text = text;
     }     
     
}

GREAT!!!
