individual columns from separate databases

I have issues doing Count aggregations in 2 different databases. 2 out of 3 following
cases fail... (But distinct count seems ok)

---------------------------------------
A similar exception was noticed with the fix to TEIID-2220, can you confirm that your
query now works on trunk (or alpha2 which should be on monday)? Alternatively can you
post ddl/vdb to reproduce the issue?

----------------------------------
It still doesn't work in Teiid 8-2 Alaph2. But I don't have a ddl or vdb file. I
am actually running in embedded mode. But I can provide an SQL statement, would it help?
Thanks.

show me how to export VDB from VDBRepository.

Steven Hawkins updated TEIID-2219:
----------------------------------
Attachment: EmbeddedServer.java.patch
There isn't a built-in mechanism like the server GetSchema operation. You can use
logic similar to the attached patch to print a schema.
We'll have to put some thought into adding some kind of a dump/getschema call for
embedded.
NullPointer Exception when doing count aggregations on two individual

Steven Hawkins resolved TEIID-2219.
-----------------------------------
Fix Version/s: 8.2
Resolution: Done
Thanks for reproduce this. I'll introduce a separate issue to cover adding some more
EmbeddedServer logic. The issue here was caused by having aggregates from each side of
the join and using count, which introduces an expression in the aggregate mapping. The
fix will be in Beta1.
