With Network tab, we are referring to something like Google Chrome
Development tools. In Chrome, right click on anything on a page and open
Inspect. The DevTools then have a Network tab showing all traffic
between the web site and the server(s) such as TopBraid. Other browsers
have similar features.
Is there anything underneath the NullPointer exception in the log, i.e.
any stack trace?

after dismissing the dialog everything seems to work fine - and
subsequent interactions with the class navigation pane do not throw

I cannot find any "tab" in TBC menu, views, EDG or SWA that I can
identify as "the network tab" - not sure what you mean
The error console shows :

What version are you on? Is the instances pane loading at all - or
is it staying blank? Is there an error in the console, or a
failing network request on the network tab?
If 5.4, could be due to missing label for class - but that should
not be an issue in 5.5+.

How is the message being reported: Through a JavaScript

Usually such things can be debugged by putting breakpoints
into the code (e.g. using Chrome dev tools), thus my
question above.
The class tree does not require labels AFAIK.

(unmodified) SWA editor throws a message "null" when
opening Class tree at a specific class
data has no instances (also throws if instances) - it
imports an ontology loaded via EDG (which a
specialisation of PROV-O).
If you ignore this, the class tree works - and if you
reopen that class it does not throw the error again -
only after reloading the editor page, the first time.
So three questions:
1) what is causing this (if known or guessable)
2) is there any way to get more useful diagnostics - such
as a stack trace or something to show where it fails
3) is there a unknown contract - i.e. something the data
_must_ do - such as have labels (in this case all classes
do) - or should it really handle any OWL class model ?
