Re: [stellation-res] Question about Merging NPE

[Jeffrey Howard <jhoward@xxxxxxxxxxxxxxx>]

Hello,

It looks like the same problem can be seen when using the remote
messaging protocol with the Stellation server rather than the direct
client communication with the database.  The server throws an NPE in a
slightly different place, but it looks again like it can't find a
parent set for the main.0 branch/revision and doesn't handle that
case.  This isn't too surprising -- whether it's done through a local
client or a server, the operations to merge are the same.

I've enclosed the exception stack trace below.
