I was little puzzled as to why you were putting in brute-force boldface and color elements on your sample. Then I realized that you were attempting to highlight things and our formatting control doesn't do that. Oops.
As usual, I have to nit-pick before addressing the real problem: "CMBrowserBean" is a class instance, not a class. So according to the JavaBean conventions, its name should start with a lower-case character.
JSF does not enforce this, but some tools and other resources may have trouble when you don't follow the conventions. At least you didn't call it a "Controller" .
The easiest way to get your controls enabled and disabled is by using their "disabled" attributes to track a boolean property in a backing bean. The valueChangeListener can do an AJAX event that causes the bean to be (selectively) updated and the disabling booleans to be set/cleared as needed. Then the reRender can cause the target controls to be re-rendered using the current (updated) disable property values.
