Removing observers

[thomthom]

How do you remove observers? What is the argument to pass on?

I've been using an entities observer to monitor the enitites of the active path. Whenever the path changes I need to remove the observers watchign the old path. But now?

The example in the manual doesn't give much of a clue. Just says observers. I tried passing my Observer class, but that didn't do anything. The remove_observer method return false every time.

That would be the same link I provided in my OP. It's not obvious to me what it does and what the observer is.

I've tried to make store the return value when I do MyEntitiesObserver.new ( myTemp = MyEntitiesObserver.new )

And then I try entities.remove_observer( myTemp ) and that returns true. But the old observers still triggers...

You need to pass the observer to the 'remove_'... You must have an entity_ or entities_observer ?

Ok. Found the problem. I was using model.active_path to cache the last path. When the last path was the model itself it'd return an empty array.
