Validation errors

[Abe90]

When I try to add a custom validation, using the method

$Model->errors->add('test', "a test");

I will return this error: Fatal error: Call to a member function add() on null

what is wrong?

I'm sorry, I have not read the last line of documentation.

(This feature is available since v1.1 or nightly builds.)

I recommend you make it more visible :-)
