How can a value as in a variable be passed from one webpage to another while executing code to set and get the value?

MyCode:

@ManagedBean(name="TestCodeBean")
public class TestCode {

@ManagedProperty(value = "#{testValue}")
private String testValue;

public String getTestValue() {
return testValue;
}

public void setTestValue(String testValue) {
this.testValue = testValue;
}


On the starting webpage:

<p:inputText value="#{TestCodeBean.testValue}"></p:inputText>
<p:button action="#{TestCodeBean.testValue}" value="TEST ME"></p:button>

On the finishing webpage:

<h:outputText value="#{TestCodeBean.testValue}"></h:outputText>

What am I doing wrong? :?

As far as I can understand now I just need a proper method to do the transfer and link that to the button.

As for what needs to be in this method I have no idea! :D

I've not used JSF with annotations but I don't think you need the @ManagedProperty annotation on the instance variable. The properties are implicitly part of the managed bean without needing further annotations.

I think you'd use that @ManagedProperty annotation to dependency inject another managed bean or static value into your managed bean -- similar to the way you would use Spring "ref" properties to refer to other beans as dependencies.

Can anyone see something wrong with this? :?


<h:commandButton action="#{TestCodeBean.sendData}" />

The error:


Property 'sendData' not found

Method in TestCodeBean:


public String sendData(){
return "/testOutput.xhtml";
}

The method name needs to be getSendData(). JSF (like JSTL) uses the implied property name rather than the actual name of the getter/setter.

Yes I got things working now!

I have a value from one page being displayed on my other page. :)

Only quite minor problem I have is that the Primefaces widgets are not themed for some reason. They look like plain JSF widgets but I used primefaces ones. (for example - <p:button></p:button>)

Its only a minor issue though... I don't care.. that much but I do like things that look nice! :D

Funny how I am kinda replying to myself but just to let ye know that I fixed this problem too!

Make sure to use <h:head></h:head> tags instead of <head></head> for primefaces! :)
