I found some good hints in the Rich-Faces Developer Guide
-you need a few lines of JavaScript though;(
The guide refers to a Rich-Faces Wiki article and a forum posting.

I have slightly modified the solution. On top of the page (outside the modal panel) I added a hidden form field that just indicates if validation messages exist.

The method property hasMessages is implemented as follows:

public boolean isHasMessages() {
	return FacesContext.getCurrentInstance().getMessages().hasNext();
}

The button uses the oncomplete attribute to test the hasMessages element with a little bit of Javascript.
