Gustavo,
This uses Wonder's ERXKey syntax which I like the best:
EOQualifier qual =
WG
.TSXWG
.dot
(TSxWG
.TRANSLATIONSET
.dot
(TranslationSet
.TOUSER)).contains(((Session)session()).authenticatedUser());
That should give you a qualifier that when applied to an NSArray of WG
objects will filter it down to only the WGs that are associated with
the authenticatedUser().

Yep ((Session)session()).authenticatedUser is returning a USER.
I know that when I try to qualify a User given a name I will gt a
good qualifier..
now as Chuck said I need all TRANSLATIONSET for that given user.
The relationship between TRANSLATIONSET and USER is called toUser,
so Im using the
EOQualifier tsQual = new ERXExistsQualifier(ERXQ.
equals(USER.NAME_KEY,
((Session)session()).authenticatedUser().name()),
TRANSLATIONSET.TO_USER_KEY);
to get that.
now if I potition myseld to get all the WG that contains the
TRANSLATIONSET with a specific USER I must use tsQual, so I tought
I could use it from _WG but the relationship between WG and
TRANSLATIONSET is a many-to-many having a join table WGxTS, and this
table has no name, that;s hy I was thinking that Im in the wrong
place. no?

Ok this is what I did. but is not working, I have an error in the
generated sql or somehting.. becuase it says
java.lang.IllegalStateException: sqlStringForKeyValueQualifier:
attempt to generate SQL for

failed because attribute identified by key 'name' was not reachable

I guess is becaus Im trying to search in the wrong place..
It's not an error in the generated SQL, it's an error in your
qualifiers. To be honest, I can't follow your model, but EOF is
telling you the problem: you've tried to qualify an entity on a key
that doesn't exist in that entity. Specifically, 'WGxTS' has no key
called 'name'.
As an aside, earlier you wrote:
but so far what I have from the user is the name... so I will need
to get the userID something like toUser.NAME.eq(name).
Yet here:
EOQualifier tsQual = new
ERXExistsQualifier(ERXQ.equals(USER.NAME_KEY,
((Session)session()).authenticatedUser().name()),
TRANSLATIONSET.TO_USER_KEY);
Don't you have the User? What's Session.authenticatedUser()
returning if it's not a User?
