Hi Luiz,
This is in the JavaDoc for this method:
* Updates rows described by the qualifier. Note that the values and the
qualifier need to be on an attribute
* and not on a relationship level. I.e. you need to give
relationshipForeignKey = pk of object instead of
* relatedObject = object. The newValues dictionaries also holds foreign
keys, not objects.

Subject: Exception Updating Rows When Qualifier Has Relationship
Hello, I`ve been trying to use the method updateRowsDescribedByQualifier of
ERXEOAccessUtilities class but I`m facing a problem.
The method updateRowsDescribedByQualifier requires the following parameters: an
EOEditingContext, a String that represents an entity name, a qualifier and a
NSDictionary of target fields to be updated.
The problem I`m facing is that in my qualifier I`m using a relationship, the
qualifier is Activity.OWNER.is<http://Activity.OWNER.is>(user);, in this case
OWNER is the relationship between Activity and User.
As exception I`m getting the following stack trace:
java.lang.IllegalStateException: sqlStringForKeyValueQualifier: attempt to
generate SQL for er.extensions.qualifiers.ERXKeyValueQualifier (owner =
(User)'<User pk:"5">') failed because attribute identified by key 'owner' was
not reachable from from entity 'Activity'

Could someone help me to understand a way to solve this?
Thanks.
