Using zmNinja, the API reports E_NOTICE errors
Notice (8): compact(): Undefined variable: subject [CORE/Cake/Utility/ObjectCollection.php, line 128]
Notice (8): compact() [<a href='http://php.net/function.compact'>function.compact</a>]: Undefined variable: subject [CORE/Cake/Utility/ObjectCollection.php, line 128]
Notice (8): compact() [<a href='http://php.net/function.compact'>function.compact</a>]: Undefined variable: subject [CORE/Cake/Utility/ObjectCollection.php, line 128]
Notice (8): compact() [<a href='http://php.net/function.compact'>function.compact</a>]: Undefined variable: subject [CORE/Cake/Utility/ObjectCollection.php, line 128]
and zmNinja will not work...
there is a better way, but i think disabling E_NOTICE error is way easier
