Yii - Bug que vai derreter seu cérebro - Trying to get property of non-object

Veja bem,

Se você define no MySql um campo como decimal (9,7) o gii do yii gera a seguinte regra
array('latitude, longitude', 'length', 'max'=>9).

Quando você executa o método save do model você receberá este erro

decimal (9,7) significa 9 casas decimais no total com 7 casas decimais possíveis a direita.

Ou seja

'max'=>9 faz sentido.

Porém o yii não leva em conta o ponto decimal e o sinal para dizer se é positivo ou negativo.

Ou seja, o correto é

'max'=>11 

Ain't that a bitch?
