I'm confused. Sounds like we approach this thing from different
angles. So let's sort it out.

I have never developed IDE stuff, but I would think that when
debugging, you start a JVM, create a singleton DebuggingService in it
(or let FreeMarker create it) and connect to it, add the breakpoints
to it (which might be in different FTL-s, or in the same FTL... it
doesn't matter), then let the actual application start. Then you sit
and wait for the breakpoint events while the application is running.
If there's an event, you try to figure out which .ftl file is it in,
and open that file in the editor. Is it how it goes, roughly?

If so, how did you use one DebuggingService per FTL file (as opposed
to one per JVM, or at lest on per Configuration)? How do you inject
the DebuggerService into the Configuration instances that the
application creates internally? (Actually I can imagine ways, like
instrumentation, but that's quite a hack.)

Or, maybe, are you launching the templates directly from the plugin,
which also creates a dummy data-model? That would be an useful extra,
but it's not general purpose debugging of course.
