Accessing UI Components within Managed (Backing) Beans

[Lucas Vicente]

Hello all,

I use to program in .Net and now I'm trying to learn Servlets, JSP and JFS.
I have a question regarding accessing ui components in managed (backing) beans like is done in .net's codebehind.
For example if I have a hutputText (Label ?) in the UI how do I access this component in the managed bean to change its attributes, to make it visible or not and etc ? Do I need to use another lib besides the regular JSF libs ?
I'm asking this cause I downloaded the Netbeans 6.0 RC2 and noticed that it uses another lib instead the regular jsf one to make this kind of behavior.

Thanks in advance

Lucas

<h:outputText rendered="#{myBean.someProperty}" ....... />

MyBean.java

public boolean getSomeProperty() {
   // return false if you want to hide the text field
}

Hello Richard,

I see what you're saying work fine but this was not exactly what I was looking for. I think that I found now what it is but I'm not completely sure if this is a good approach.
I found something like this:

  
<h:outputText id="myOutputText" binding="myBean.myOutputText" />

MyBean.java

 
...
// Component declaration
private HtmlOutputText myOutputText;
...
// Getters and setters for the component
public void setMyOutputText(HtmlOutputText myOutputText) {
    this.myOutputText = myOutputText;
}
 
public HtmlOutputText getMyOutputText() {
    return myOutputText;
}
...

Doing this way I have access for the component's attributes inside of MyBean so then I could do something like this:

  
...
public void doButtonClick() {
    // Set a new value to the label
    myOutputText.setValue("Test");
    ...
    if (myOutputText.getValue().equals("hide")) {
        // Hide the label
        myOutputText.setRendered(false);
    }
}
...

I think that this is the other people's question too and I hope this topic could help them.
But thank you for the reply, I really appreciated it.
