Why am I getting the above error message?
I have defined one .js file called login.js which has one function in it called login():
function login(){
importClass(Packages.test.User);
var msg = "Success";
var obj = new User();
obj.getUser(cocoon.request.get("password"));
while (true){
cocoon.sendPageAndWait("login.jx", { " : msg} );
if (obj) {
if (obj == null){
error = "The username and password combination you entered does not exist. Please try again.";
}else{
break;
}
}
}
cocoon.sendPage("success.jx", {" : msg} );
}
What I am try to achieve here is:
1. Instantiate a user object
2. call the method getUser and pass it 2 parameters
3. while (true), while the username and password do not exist redirect the user back to the login page
My form is defined as (login.jx):
<?xml version="1.0"?>
<html xmlns:jx="http://apache.org/cocoon/templates/jx/1.0">
<head>
<title>beyaRecords - Login</title>
</head>
<body>
<h2>${msg}</h2>
<form method="post" action="${cocoon.continuation.id}.kont">
<input type="text" name="username"/>
<input type="text" name="password"/>
<input type="submit"/>
</form>
</body>
</html>
The full stack trace is :

Ok,
i have discovered that the following line caused my sitemap to bomb out:
<map:flow-interpreters default="JavaScript"/>
What does this line do, is it required, will commenting it out prevent flowscript from working properly????

Hi,
ok, so I have been using actions thus far to perform things like login, and now discover the beauty and simplicity of flowscript. So why actions? Anyway, I want to convert an action I currently have to check a users login details to flowscript. So my question is, what do I need to do? My user class is of the getter and setter variety and in my sitemap I have the following code to read the user/password details into the action:
<map:match pattern="login">
<map:act type="auth-login">
<map:parameter name="handler" value="beyarecords"/>
<map:parameter name="parameter_name" value="{request-param:user}"/>
<map:parameter name="parameter_password" value="{request-param:pass}"/>
<map:redirect-to uri="registerd_user_area"/>
</map:act>
<!-- authentication failed: -->
<map:redirect-to uri="login.html"/>
</map:match>
I now want to change this code so that it can read the values into a flowscript, which in turn queries a user object ( User user = User.getUser(userName, userPassword) ). If the user does not exist i want the user to be re-directed back to the login page, otherwise they are re-directed to my protected area:
<map:match pattern="registerd_user_area">
<map:act type="auth-protect">
<map:parameter name="handler" value="beyarecords"/>
<map:aggregate element="home">
<map:part src="cocoon:/support/beya-menu"/>
<map:part src="cocoon:/support/contract-summary"/>
<map:part src="context://beyarecords/content/adv-xyz-01.xml"/>
<map:part src="cocoon:/support/banner"/>
</map:aggregate>
<map:transform type="xslt" src="style/home-page.xsl"/>
<map:call resource="serialize"/>
</map:act>
</map:match>
Of course I appreciate that those parts of my sitemap which used the map:act type="auth-protect" would now need to be changed to reflect using a flowscript instead, something like:
<map:call function="userLoggedIn"/>??? In the above instance, how would I still utilise the map:aggregate???
