Attribute "for"

[Josué Alcalde González]

I am extending HtmlOutputLabel adding a "*" when its for component is
required.

I am almost successful but I am having a problem.
The "*" is not rendered the first time the page is rendered.

The problem, is that findComponent does not find the "for" component
using findComponent the first time:




EditableValueHolder uiFor = uiLabel.getInputFor();
if (uiFor == null || !((EditableValueHolder) uiFor).isRequired())
        return;
