Hi
I'd love to log this as a bug but I can't track down why.
This is the code for a ResultFilter with IronRuby MVC
class LightspeedFilter < ResultFilter
def on_result_executing(context)
# put before result filtering code here
end
def on_result_executed(context)
context.controller.uow_scope.dispose
end
end
I can see that it has a uow_scope instance but as soon as I call dispose on
it it fails which didn't use to happen. I can't reproduce the scenario in
the console which makes it harder to figure out what is going wrong. I've
also tried putting Dispose, dispose(true), Dispose(true) but none of them
work.
I'm going to pull that code out and replace it with another OR/M.
