A user reports that he is not able to select "other components and versions except the first one added to the product"

He has this setup:

Product
-Component
--Version
-Component
--Version
-Component
--Version
-Component
--Version
--Version

I've attached a diff that should fix part of this problem. It was caused by having multiple components under the same product and construct_pcv_select() had a small bug.

However, there's still a bug that will not show the product name if it does not have any versions immediately underneath it, only components.

This full patch should fix the entire bug. It will look a little weird if you don't have any immediate versions under a product, but I can't really do anything about that until 1.1. This should get everything working, however.

Hello, I had applied the patch but problem still happening, but this time different...
Between each component, appears a space (blank line) and I can select only this blank line, not the wished component.

Do your components have versions underneath them? You cannot select a component by itself: you need to have a version to select. So, either make sure the product OR component has a version underneath it.

After applying the full patch I got a new bug. (See attached image)
It repeats the versions of components before presenting the component in the list. (I'm naming versions with characters instead of numbers)

Can you please take a screen shot of the product manager in the control panel so I can see your setup. I'll then try to reproduce this and create another patch.
