I use Common Navigator Framework for represent my model, but sometime (don't understand a reason) one of eAdapters becomes to null. And when I try to add some child to this element I have an exeption.
Can anybody explain me the reason and how to avoid it?
Thanks,
Dmitriy.

Dmitriy,
If the code adding the adapters needs to be fixed where ever it may be.
It might well be the case that your code is doing things in some thread
that's causing adapters to be added in your thread. I know nothing
about the specifics of the common navigator framework, so I can't help
track down such a problem...
