Contemplate and Ecommerce

My objective : personalise the design of a personalised product content.
Problem encountered : contemplate do not support the a compiled content new content type - product.

Dear Drupalers,

I've created a new content type through the CCK module, let's call it "Ipod". The content type Ipod contains two fields: a text area and a image, as long I want to depict Ipods.

I want also to sell my Ipods, so each time I create a new Ipod node, I add it to the store (as a apparel product) and I add product variations, because my Ipod don't have same storage capacity and color. At this point, everything works fine: there is no incompatibility between the CCK module suite and the Ecommerce modules suite.

As I want to personalise the theme of my Ipod nodes, so I use contemplate. But when I do so, the products informations (price, product variations, add to cart link) disappear. In other words the contemplate code does not include the product part, and as long as it don't support a detailed personalising scheme of the core / other modules (such as image or product).Indeed, if I simply fill contemplate fields as follows...

<?php print teaser ?>

<?php print body ?>

...all informations are displayed (Ipod content and Product content), yet I cannot personalise the content design anymore: the contemplate module is useless.

Thank you for the help.
