Re: CAY-1345) enum construction requires string name of enum
What do people think of this as a solution? And what about getting that into 3.0? This really is a bug in 3.0 I think, since the whole concept of the interface ExtendedEnumeration is flawed at the moment.
I haven't done any testing of this yet, but Marcin was going to see if he could write a few unit tests and also test it inside our own application.

Re: CAY-1345) enum construction requires string name of enum
Posted by Michael Gentry <mg...@masslight.net>.
The extended enums used to work just fine translating string/int values
to/from the DB. I'll have to look at this in more detail later.

Re: CAY-1345) enum construction requires string name of enum
Posted by Andrey Razumovsky <ra...@gmail.com>.
Since CAY-1261 we started to inject qualifier values automatically at
creation of the object. So, we need to do operation reverse to
getDatabaseValue() to have newly created object's ProductType=qualifier
value. Particularly, this line caused te error:

org.apache.cayenne.BaseContext.injectInitialValue(BaseContext.java:407)

OK, great. But I'm confused how CAY-1261 caused the problem. I can't see any code anywhere that would ever have made this work.

Re: CAY-1345) enum construction requires string name of enum
Posted by Andrus Adamchik <an...@objectstyle.org>.
Yep, the fix looks good to me (and this *is* a bug in 3.0). One note:
type.isAssignableFrom(ExtendedEnumeration.class)
should be
ExtendedEnumeration.class.isAssignableFrom(type)

Re: CAY-1345) enum construction requires string name of enum
Posted by Andrey Razumovsky <ra...@gmail.com>.
Looks fine. It's a regression in B1 (caused by CAY-1261), and it'll be great
if you committed the fix. setProperty() should work correct for
ExtendedEnums as well
