When using a ONE_TO_ONE relationship in Rdo I could not access a  
related data field. I tracked the problem down to Base.php, function  
__get(). Consider lines 122 to 136 where a SQL search for the attached  
record is conducted:

         switch ($rel['type']) {
         case Horde_Rdo::ONE_TO_ONE:
         case Horde_Rdo::MANY_TO_ONE:
             if (isset($rel['query'])) {
                 $query = $this->_fillPlaceholders($rel['query']);
                 $this->_fields[$field] = $m->findOne($query);
             } elseif (!empty($this->{$rel['foreignKey']})) {
                 //$this->_fields[$field] =  
$m->findOne($this->{$rel['foreignKey']});
                 $this->_fields[$field] =  
$m->findOne(array($rel['foreignKey'] => $this->{$rel['foreignKey']}));
                 if (empty($this->_fields[$field])) {
                     throw new Horde_Rdo_Exception('The referenced  
object with key ' . $this->{$rel['foreignKey']} . ' does not exist.  
Your data is inconsistent');
                 }
             } else {
                 $this->_fields[$field] = null;
             }
             break;

For unknown reasons everything works for a MANY_TO_ONE relationship,  
using the same code.
Anyway, I used the available information to define a more specific  
search in line 129:

$this->_fields[$field] = $m->findOne(array($rel['foreignKey'] =>  
$this->{$rel['foreignKey']}));

and this made it work for all types of relationship.
