Programmatically import configurable products - php

Question

I use cron to import products in the database. Products are imported but the association between configurable products and simple products is not done correctly. The association is done every new product but at the end, only the last product imported remains. Please find the function I use below.
==EDIT==
This function is under community>Bmservices>Polaris>Model>Observer
It is called by a cron defined in config.xml that work. I am sure that the function is called as I am logging in it and the log is filling with the proper information.
==END OF EDIT==
I get the $line from csv.

Is there something I miss.

Answer 1

I found my mistake and I could not believe it got me stuck for more than a week. In case somebody encounter the same issue, the answer lies in the website ids. I did not affect any so the product did not exist in any store so it was affected but not visible on the product page. I can not explain why I had it on admin and in the database but now everything is ok.
