I have 2 pages, inputForm.xhtml and outputPage.xhtml.
In inputForm.xhtml, there are 1 textfield and 1 checkbox. When user clicks submit button, the values are passed to outputPage.xhtml in URL.
The value of textfield can be passed correctly. However, no matter the checkbox is checked or not, the parameter in URL is always false.
e.g. http://localhost:8080/jsf-web/outputPage.xhtml?c=false&n=franz
I am using myFaces 2.1.13. I really have no idea how to fix that. Thanks.

Finally I tried primitive int and it is passed as 0 no matter what value I input.
Therefore, I tried Boolean, Integer and found that the value I input can be passed correctly in URL.

Functionality:
Here we are navigating from index.xhtml to "register" flow scope, containing register.xhtml, register-flow.xml, confirmation.xhtml
From register.xhtml we navigate to confirmation.xhtml.
Issues:
1) I want to make a "back" output link in confirmation.xhtml to navigate back to register.xhtml
<h:outputLink value="register.xhtml">
<h:outputText value="back"></h:outputText>
</h:outputLink>
But this is not working, its giving following error when I click on "back" on UI
"WELD-001303: No active contexts for scope type javax.faces.flow.FlowScoped"
Interesting thing is <h:commandButton> is working instead.
2) Why can't we directly run a file in directory ("register").
Its giving following error:
WELD-001303: No active contexts for scope type javax.faces.flow.FlowScoped
I am confused. Please help me?
I've the below portlet view.xhtml:
<?xml version="1.0"?>
<f:view xmlns="http://www.w3.org/1999/xhtml"

xmlns:p="http://primefaces.org/ui">
<h:body>
<h:form>
<h:commandButton value="TESTButton" action="#{navigationViewBean.submit}" />
<h:outputText value="TESTGetter: #{navigationViewBean.testField}" />
</h:form>
</h:body>
</f:view>
And this managed bean:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
#ManagedBean(name = "navigationViewBean")
#RequestScoped
public class NavigationViewBean {
private String testField;
public boolean lol = false;
public void submit() {
System.out.print("TEST BUTTON INVOKED");
}
public String getTestField() {
System.out.print("TEST GETTER INVOKEDx");
return testField;
}
public void setTestField(String testField) {
this.testField = testField;
}
}
The only thing I try to do, is to call a method which prints something to my console. The problem is that no matter what I do, the action method is never invoked. The getter method is properly called.
What am I doing wrong?
Im not sure why, but after adding this line to my liferay-portlet.xml it fixed it.
<requires-namespaced-parameters>false</requires-namespaced-parameters>
And here the whole block:
<portlet>

If you are using JSF 2, you can have something like this in your index.xhtml (but it can be easily converted to earlier JSF version):
...
<h:form>
<h:inputText id="guestName" value="#{party.newGuest}"/>
<h:commandButton value="Add guest" action="#{party.addGuest()}" />
</h:form>
...
And, in Party.java:
private String newGuest;
....
public String getNewGuest() {
return this.newGuest;
}
public void setNewGuest(String guest) {
this.newGuest = guest;
}
....
public void addGuest() {
guests.add(newGuest);
newGuest = null;
}
No need for Guest.java in this use case. Could be done in a nicer way, though.
I have a commandButton in JSF 2.0 with a actionvalue that I want to call a method in a bean and otherwise do nothing. However when I click on it, it redirects to the previous page.
This was programmed in java 1.7 in eclipse using glassfish 3.1.1.
Here is the code for the welcome.xhtml file where the commandButton is (showDetails) but there are many other files, so I have included a link to a WAR file so it is possible to check everything out. If i change the action attribute to point to a method that does not exist I will not get an error, I will again be redirected to the frontpage.
The program is started from the index.html file. After importing remember to leftclick on the project, go to properties>project facets and tick of JavaServerFaces 2.0
The relevant code:

As shown in every decent JSF book/tutorial, you should be using <h:form> instead of <form>.
<h:form>
<h:commandButton value="Back" action="index" />
</h:form>
<h:form>
<h:commandButton value="Show details" action="#{userBean.changeRenderDetails}" />
