Problem with a my components

[nikiC]

Hello everyone,
I recently created a component that I need to generate SKUs. This component should be included in the product view on the administration side.

I'm having a problem; I'm getting the error JLIB_APPLICATION_ERROR_MODEL_GET_NAME.

Can you tell me why? I tried everything, and I ended up asking for help first from nicepage and then from you.

Let me know if you have any ideas...

I'll leave you the link to the RAR file containing the program and a description of the files.
