ContentType.FieldLinks.Add() issue with hidden and required

Question

I have a feature that does the following in the feature activation Code :

Creates a new SiteColumn (Type=Text, Hidden=False and Required =True)
Set the french version of the Name (using CurrentUICulture switching)
Create a new ContentType
Add the SiteColumn to the new Content Type
Create a new list
Attach the ContentType to the list

But that causes some unexpected behaviors.

Sometimes my Column in the list is Hidden=True, sometimes Required=False. It seems to be totally Random.

It seems related to the ContentType.FieldLinks.Add() since the values are wrong in the content type.

Anyone faced something like that before?

Thanks

Try to set values in upper case - Hidden="FALSE" and Required="TRUE" — Alexander, Commented Aug 16, 2012 at 16:47
I may have been unclear. That is done through code and those properties are boolean, I cannot set String values there. sorry. — danbord, Commented Aug 16, 2012 at 18:30
Unfortunately not, I did not find any way to resolve the issue (or at least I don't remember how I fixed it) sorry. — danbord, Commented May 27, 2013 at 17:13

Have you made the list content type enabled - SPList.ContentTypeEnabled?
Try to set the 'Required' property on the fieldlink from the content type and not directly on the site column itself
You don't have to set the 'Hidden' property, it's false by default.

I just posted an answer on a similar question that I think is the same root cause:
