PHP should report the exact line number where it happens. If not, try to define YII_DEBUG set to true in your index.php or vhost configuration.

Such errors happen oftern when you try to read a property from an object retrieved by some method but that method returned null.

If you had defined the states as a relation in the Countries model you don’t have use findByAttributes to get them, just read them as an attribute of $country.
