I don't know if this is a clue but this is what I see in debug, when
it's dealing with the TeamFan metadata. Just not sure if
"HandlerFieldStrategy" is correct or not..
2008-10-16 10:56:08,472 [btpool0-1] DEBUG openjpa.MetaData - Resolving
field "[EMAIL PROTECTED]".
2008-10-16 10:56:08,472 [btpool0-1] DEBUG openjpa.MetaData - "fan" has
mapping strategy "org.apache.openjpa.jdbc.meta.strats.HandlerFieldStrategy".

thank you for replying!
Fan and TeamFan are entities of course. They extend a MappedSuperclass.
Here are the four classes involved in this query. Fan and TeamFan
extend HBaseIdCreateTime, which extends HBaseId.
And just to recap from last email:
I load a "Fan" object via the "fbId" field, and that works just fine.
Then I try to load a "TeamFan" object via that "Fan" object just loaded,
and a "teamId". But it complains that the Fan is not a valid type:
<openjpa-1.2.0-r422266:683325 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: The specified
parameter of type "class com.protrade.fandom.data.entities.Fan" is not a
valid query parameter.

Hi Fernando,
Is TeamFan also defined as an entity and is there an inheritance
strategy defined for the Fan - TeamFan hierarchy? If not, you'll need
to make sure you have a valid JPA inheritance hierarchy & strategy.
If this is the case, could you post your entity classes or even
better, a failing test case?
