NULL values in Live table

I'm having a slightly weird problem. I'm trying to create a dataobject that will appear as a page in the site tree.

The basic code is like this:

$product = new Product();
$product->Title = "Example";
$product->ProductNumber = 666;
$product->publish('Stage', 'Live');

If I do that and then go and watch the site tree everything looks all peachy. The new product has been added as a new published page.

But if I have a look in the database tables I realize that while the Product draft table looks like its intended to all fields except the ID field in the Product_Live table is set to NULL.

So if I do a:

DataObject::get_one("Product", "ProductNumber = '666'");

It will return nothing as ProductNumber is NULL in the _Live table.

What does the "Product" class look like?

It goes a little something like this:

class Product extends Page {
    public static $db = array(
        "ProductNumber" => "Text",
        "Preamble" => "HTMLText",
        "ProductDescription" => "HTMLText",
        "OldItemID" => "Int",
        "OldProduct_Description_X" => "HTMLText",
        "OldImage_Product_Number" => "HTMLText",
        "OldMID" => "Int",
        "ForSale" => "boolean",

    public static $has_one = array(
        "MainPic" => "Image"

    static $has_many = array(
        "ProductPics" => "ProductPic"

    static $many_many = array(
        'Markets' => 'Market',
        "Accessories" => "Product",
        "SpareParts" => "Product",
        "SimilarProducts" => "Product",
        "ProductContactPersons" => "ProductContactPerson",

    static $multilingual_fields = array(
        "TechSpec", "Preamble", "ProductDescription", "OldProduct_Description_X",

I've run out of both good and bad ideas now. :D

With a $product->write(); I can get it to the _Live table, but then it's not in the draft. I can't seem to have them both at the same time. Unless I go into the CMS and hit the Save & Publish button, because that takes care of it and moves it to _Live.

Forgot to mention that the data looks like its supposed to in Product_versions as well. It's just that damn _Live. Argh.
