Re: Entity name ignored in queries (0.9.6)?
Dain-
I've reproduced this problem and reported it at:
https://issues.apache.org/jira/browse/OPENJPA-142
The only workaround is to add the @Entity(name=someAlias)
annotation to the class in addition to specifying it in the orm.xml
file.

id name=id/

The following query does not work:
SELECT o FROM BasicCmp2Bean o WHERE o.lastName = ?1
But this one does:
SELECT o FROM BasicCmp2Bean_BasicCmp2Bean o WHERE
o.lastName = ?1
When the query fails, I get this message (reformatted a bit with **
added to important entries):

I kind of remember Patrick fixing a bug like this but I couldn't

Re: Entity name ignored in queries (0.9.6)?
Excellent. I added a watch for this issue and will try out the fix
as soon it is available.
In the mean time, I changed my code generator to generate classes
with the exact entity name I want :)
