CommandLink navigation doesn't work in JSF
i wanted to use the navigation-rule feature of my faces-config.xml (JSF 2.0) but I have some problems with it. I have three files (index.xhtml,index2.html,index3.xhtml) and they look like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<f:loadBundle basename="resources.application" var="bundle"/>
<head>
<title><h:outputText value="#{bundle['welcome.title']}" /></title>
</head>
<body>
<h3>1</h3>
<h:form>
<h:commandButton action="next2" id="nextpagelink" value="Next Link">Next</h:commandButton>
</h:form>
</body>
</html>
(index.xhtml, the others look similar with different actionnames and other h3-field)
My faces-config.xml has the following entries related to navigation-rules:
<faces-config

However when i click on the link in the index.xhtml file nothing happens. I don't get to the next page index2.xhtml as I thought
There are a lot of reasons for commandlink/button navigation not working, the common ones being:
h:formis missing.h:formis nested inside anotherh:form.- Validation or conversion error has occurred.
There are more, but that's as far not relevant yet I think. The code in your question is not the actual code. It looks fine and should work fine (if you add the <html> tag with correct xmlns declarations).
If in vain, I suggest to debug the POST request. What JSF phases were entered/executed? What code got executed and what not?
See also:
h:commandLinkis not being invoked (contains more possible reasons).
Try adding redirect to the navigation URL, eg. action="next2?faces-redirect=true" or a <redirect /> element to the navigation case.
But basically h:commandLink is a POSTing component, not a GETting one. Better to use h:outputLink in this case IMHO.
