Today I had a problem when I want to add related product to Magento Professional 1.9.0.0., it did not work. After some tracing thrown errors and comparing files with other Magento versions I found missing part. Magento Professional has missing lines of code in Related.php. So, if someone stuck on the same problem, here is the solution!
