Hello

(I wanted to move this post from general question to dataobject manager. sorry if i did something wrong)

Based on Aram great tutorial :
http://www.ssbits.com/tutorials/2010/dataobjects-as-pages-part-2-using-model-admin-and-url-segments-to-create-a-product-catalogue/

I'm building a website for a galery.

I have a main DataObject called 'Oeuvre' every 'Oeuvre' has title, images etc..
Then I can link any of them to a ArtistePage (see screenshot ):

$Artistes = DataObject::get('ArtistePage');
$f->addFieldToTab("Root.Artistes", new CheckboxsetField('Artistes', 'Artistes', $Artistes));

It works perfectly with the main language sitetree but if I translate an ArtistPage using the site tree translation the link is broken.

Is there a way not break the link between a translated page and the data object (best) or a way to relink them manualy.

Thanks a lot

Below the full code

<?php

class Oeuvre extends DataObject
{
static $db = array(
'Titre' => 'Varchar(255)',
'Annee' => 'Text',
'TechniqueFr' => 'Text',

$count++;
}

//Test whether the URLSegment exists already on another Oeuvre
function LookForExistingURLSegment($URLSegment)
{
return (DataObject::get_one('Oeuvre', "URLSegment = '" . $URLSegment ."' AND ID != " . $this->ID));
}

//Generate the link for this Oeuvre
function Link()

//if we are on a Artiste page return that
if(Director::CurrentPage()->ClassName == 'ArtistePage')
{
$Artiste = Director::CurrentPage();
}
//Otherwise just grab the first Artiste this Oeuvre is in
else
{
$Artiste = $this->Artistes()->First();

//Check we have a Artiste then return the link

return $Artiste->absoluteLink() . 'show/' . $this->URLSegment;
