[jboss-jira] [JBoss JIRA] (DROOLS-172) Multiple proxy instances for same trait

[Davide Sottara (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12782989#comment-12782989 ] 

Davide Sottara commented on DROOLS-172:
---------------------------------------

Fabian, I'm out of town this week and the connection is bad, sorry if it takes long to answer.
It is actually expected that two proxies, one for B and one for C, are created. B and C may expose totally different properties of an underlying object. 

I see, however, the problem: the query returns two "A" instances, even if we are talking about the same "core" object.

Some changes are being merged that improve unwanted side effects of this implementation choice in "modify", but I didn't work on queries yet.

Can you try if 

query "traitA"
 a : Object( this isA A )
end

works better?
