Validate check boxes?

[riotrellik]

I have been given a project that uses RichFaces... I have never used it, and don't know much about AJAX or JS.

What I am doing, or trying to do is have two checkboxes, I need at least one of them to be chosen, and I need it to not submit if at least one or both is not checked.

I have figured out the very easy to use form field validation, but have found no documentation or example of a multiple check box validation.

Any help would be greatly appriciated.

Thanks you.

example code:

<h:selectBooleanCheckbox title="participantAccess" value="#{dcSite.userParticipantAccess}" />PARTICIPANT
<f:verbatim>
<br />
</f:verbatim>
<h:selectBooleanCheckbox title="sponsorAccess" value="#{dcSite.userSponsorAccess}" />SPONSOR

if this were ActionScript I would right a function that would see if one or both had been checked, but I am not sure how to go about this in this.

So been messing around, searching like crazy,

And I have an idea, what if I add a function to the bean that has an if / else statement that would logically run through and make sure that at least one of the two checkboxes was checked?

public void validateSiteCreation(userParticipantAccess,userSponsorAccess) {
     if ( userParticipantAccess.equals(null) && ( userSponsorAccess.equals(null) {
          //reject submission
     } else if ( userParticipantAccess.equals(!null) && ( userSponsorAccess.equals(null) {
          //send submission
     } else if ( userParticipantAccess.equals(null) && ( userSponsorAccess.equals(!null) { 
          //send submission
     }
};

Hi Pete,

Take a look at rich:graphValidator. Another options are discussed in this thread: http://community.jboss.org/thread/139135?tstart=0 or search Google for examples of cross-field AJAX validtion.
