Hi Felix - One approach to consider would be to set immediate="true" on seelctOnceChoice A. This will force it to be validated/updated before all of the other non-immediate components. Then, in your valueChangeListener for selectOneChoice A, you should be able to call FacesContext.renderResponse() to skip over validation/update of the rest of the page - thus skipping over any required field validation.
BTW, there is a great wiki on the "immediate" attribute here: http://wiki.apache.org/myfaces/How_The_Immediate_Attribute_Works Hope that helps!
