I'm using (Project Wonder's) ERXEC, since I use several editing contexts, but I'm seeing this in my log:

What does that mean? Is there some non-ERXEC editing context around, or is some ERXEC not locking?


The ERXEC is not locked, you could activate the debug log to get a stack trace and the detect the origin.


OK. Things look like this:

I'm still lost. What should I do about this? The display group does a fetch(), but what am I doing wrong here?
