I have implemented Freemarker as a template engine that returns html to an xpage via serverside javascript. I’m glad to say this works perfectly 
However, in Freemarker you can extend the template engine by making custom directives that are implemented from a Template interface in a custom class. This also works fine, at least with a simple Hello World example.
Of course I want to extend the template so that it can read Notesdata, and to do that, I need to create a NotesSession. The directive class is instanciated once, and kept around, so I can’t start passing Notes classes around, as they will be recycled.
This guy has a similar problem: http://www-10.lotus.com/ldd/nd85forum.nsf/5f27803bba85d8e285256bf10054620d/2de9170c5553accf8525763a00640cbe?OpenDocument&Highlight=0,createSession
So I either Session==null when extending the AgentBase or I get an “Cannot create session from agent” when using the other methods of creating a session.
So, my question: Does anybody have any clue as to how this could possibly be solved?
I am adding my stacktrace, if you can get any meaning from it.
regards,
Bjørn
