Im come across a very strange error, which i cant make heads of tails with, when using the include_related advanced get.

So, i'll brief try to explain.

I have a tables called 'tasks', 'flags' and 'surveysFurnitures'
I have the relationship tables: 'flags_tasks' and 'surveysFurnitures_tasks'

Tasks has a

Code:

var $has_one = array("flag", "surveysFurniture");

SurveysFurnitures has a:

Code:

var $has_one = array("task");
        var $table = 'surveysFurnitures';

And Flags has:

Code:

var $has_many = array("task");

Relating and accessing task to flag information works fine, no problems.
Using the code,

Code:

$task = new Task();
        $task->where('id', $pointNumber);
        $task->include_related('surveysFurniture', NULL, TRUE, TRUE);
        $task->get();

relating tasks to surveysFurnitures generates this error

A Database Error Occurred

Any ideas at all from anyone?

Many Thanks
