Using Pimcore 11

I have a Data Object (Product) with a picture (Type:Image) in it. I want to set upload path dynamically based on Product->productCode but I could not find any way to do it.

Using event listeners for preAdd and preUpdate:

• I tried setting Product->getPicture()->setUploadPath(..): method undefined
• I tried setting Product->getPicture()->setPath(..): no error but no action also

Uploaded images either raise exception (no method) or end up in _default_upload_bucket

I am clearing caches on every bit of change…
