I placed a copy of Login.java under screen/ directory. I assume that
this Login.class file will be executed prior to the Login.vm file. Here
is my Login.java file:
public class Login extends VelocityScreen
{
public void doBuildTemplate(RunData data, Context context)
{
context.put("nextTemplate",
data.getScreenTemplate().replace('/',',')); try {
isAuthorized(data); }
catch (Exception e)
{ }
}
protected boolean isAuthorized( RunData data ) throws Exception
{
boolean isAuthorized = false;
AccessControlList acl = data.getACL();
if (acl==null || ! acl.hasRole("turbine_root"))
{ this.doRedirect(data, "Login.vm");
isAuthorized = false;
} else if(acl.hasRole("turbine_root")) {
isAuthorized = true;
}
return isAuthorized;
}
}
In my Login.vm file, I have this line to read the info:
<form method="post"
action="$link.setAction("Login").setPage("$nextTemplate")">
but $nextTemplate did not get passed... where did I do wrong?
