Bootstrap 3 in Liferay 6.2 works (at last)!
Liferay 6.2 is nice, but the guys working on the themes, should make a time travel in the past and use bootstrap 2.3... They don'y like it at all.
There are many articles in the web about using bootstrap 3 in a liferay 6.2 theme, but all of them had problems or didn't work at all.
Marcos Castro, found a solution in this post, we tried it out and it worked really well.
Now, we can see a smile on the face of the web developers again.
