Af:table - Programmatic mandatory check on a column

Question

I have a usecase wher in, i need to programatically apply a mandatory check on a column inside a table.
User can add multiple rows in a table and only on the click of a button(say "Save"), all the rows in the table should be validated and those with missing value for mandatory column fields should be marked in RED. Say if user, adds 4 rows consecutively and he doesnt provide value for mandatory column of first and last rows, then tht specific fields should be marked in red.
Any pointers?

Hi,
create a boolen variable in managed bean and bind with mandatory field.
<af:inputText>
required="#{EditDetails.valueReqXX}"
binding="#{EditDetails.reasonCommentXX}"
</af:inputText>managed bean code :
private Boolean valueReqXX;
private RichInputText reasonCommentXX;
    public void setValueReqFhlmc(Boolean valueReqXX) {
        this.valueReqXX = valueReqXX;
    public Boolean getValueReqXX() {
        return valueReqXX;
    public void setReasonCommentXX(RichInputText reasonCommentXX) {
        this.reasonCommentXX= reasonCommentXX;
    public RichInputText getReasonCommentXX() {
        return reasonCommentXX;
public String buttonAction()
                valueReqXX = true;//or false based on logic
                AdfFacesContext.getCurrentInstance().addPartialTarget(reasonCommentXX);
return null;
