getparentnode and custom validation rule problem

I wrote a model that act as a tree (mymodel).
In mymodel.php file I coded some custom validation rule.
One of the rules is like the following:

function testmyfield($check) {
$grandfather = $this->getparentnode($this->data['Category']
['parent_id']);
if ($grandfather)
{
$condition=array('Category.id' => $grandfather['Category']
['id']);
$ret=$this->field('afield', $condition);
if ($ret)
return false;
}
return true;
}

When this validation rule gets executed $this->data changes after
getparentnode().
Before it is an array with the values entered in the form.
After it is an array like the following:

[Category] => Array
(
[parent_id] => 23
)

[P1] => Array
(
)

(P1 is a model related to Category)

The record gets saved with some of the (required and not empty) fields
empty. :-(

I don't understand if this can be a bug or if I'm doing something
wrong or in the wrong place.

Thank you
