Attaching patch - simply moved the prerender logic up to the top of the renderComponent method. The rest of renderComponent is still bypassed during rewind.

> The FieldLabel component prerenders its associated field to allow validation decoration to work properly.  However, it only prerenders the field during the render cycle and not during the rewind cycle. If there are any form components after the FieldLabel but before the FieldLabel's field, the render sequence will differ upon rewind and throw a StaleLinkException. The fix should be that FieldLabel always calls to form.prerenderField, ensuring a consistent render sequence.
