Is there any logging I have to set up for a particular class or package or
any configuration I have to do for that? Normally, even when it works, the
only output I see from Errai while compiling is:
0 [main] INFO Configuration - configuration scan targets
0 [main] INFO Configuration - ->
C:\Users\kjordan\Documents\NetBeansProjects\Desktop\lib\errai-persistence-1.
0-SNAPSHOT.jar
0 [main] INFO Configuration - ->
C:\Users\kjordan\Documents\NetBeansProjects\Desktop\src\java
0 [main] INFO Configuration - ->
C:\Users\kjordan\Documents\NetBeansProjects\Desktop\build\web\WEB-INF\classe
s
63 [main] INFO Configuration - caching context
'C:\Users\kjordan\Documents\NetBeansProjects\Desktop\lib\errai-persistence-1
.0-SNAPSHOT.jar:*'
188 [main] INFO Configuration - caching context
'C:\Users\kjordan\Documents\NetBeansProjects\Desktop\build\web\WEB-INF\class
es'
And I'm not even really using persistence (i.e. it's not inherited in my
.gwt.xml, but somehow it's getting run anyways either via ErraiBus or
ErraiCommons).

This is an interesting theory. You should be able to determine whether the
stub is generated or not since at compile-time the Errai generators show log
output for each stub.
You should see a log output that says: "Generated marshaller/demarshaller
for: <classname>" for each entity you've annotated.

Not sure what you mean by that, but I'm using Netbeans and my
domain POJOs
are in a separate project which gets included by my web project. The
projects compile file and I've used my domain POJOs via SOAFace's
UniversalClient and regular GWT-RPC before without issues. And they get put
across the wire with Errai, it's just when the class is in a separate
project that there seems to be a problem and my callback isn't called. So
I'm wondering if it's an issue with the stub getting generated or something.

Have you tried to include your project/jar source code in your launch
configuration
?
It sounds more like a GWT configuration problem than an Errai one.
If you're using Maven to build your project, you can read this :
