Hi,

I can only reproduce such an error when accessing the webscript as guest=true.

Best Regards,

My hello.get.desc.xml file:


<webscript>
  <shortname>Hello</shortname>
  <description>Polite greeting</description>
  <url>/sample/hello</url>
  <authentication>user</authentication>
</webscript>

So authentication is set.

Strange, but now it works.

Now I have this code:


Hello ${person.properties.userName}

<script type="text/javascript">

var logFile = userhome.childByNamePath("alf docs.txt");
if (logFile == null)
{
   logFile = userhome.createFile("alf docs.txt");
}
if (logFile != null)
{
   // execute a lucene search across the repo for the text 'alfresco'
   var docs = search.luceneSearch("TEXT:alfresco");
   var log = "";
   for (var i=0; i<docs.length; i++)
   {
      log += "Name: " + docs[i].name + "\tPath: " + docs[i].displayPath + "\r\n";
   }
   logFile.content += log;
}
prompt("Hello");

</script>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Nor is a file created, nor did I get the prompt. Why not?

Thanks.

I have the same problem when a user logs into the webscript for the first time and the user is authenticated by ldap. The webscript fails with the error below. Is there a way to resolve this.
