callback_column with a set_relation

Hi,

I've transformed results from column into a link with callback_column, it's working but when I set a relation with the other table on this column, the link disappear.

(a little bit confusing ? here is my code)

This code is working

$crud->callback_column('client_ID', array($this,'_callback_client_url'));

public function _callback_client_url($value, $row)
	{
		return "<a href='clients1/read/".$row->client_ID."'>".$row->client_ID."</a>";
	}

When I add this :

$crud->set_relation('client_ID','clients','nom');

the value in the column is Ok but the link disappear...

thx in advance
