Hi,
I think this post got lost in the shuffle a long time ago. But I'm seeing
this error today and I'm trying to resolve the conflict.
How do I deal with the parentAttachment issue?
What exactly is the parentAttachment? Maybe if I knew that I could figure
out a way to solve the problem.
Thanks,
Brendan
