Re: selectOneRadio validation error

I think you may need to use different methods in the backing bean to return the selectitems. Each question should have it's own instance of the selectItemList. You can use a factory to return the different instances of the same list.

I have a jsf page which has a series of questions on it, each with radio select for the answers. Each of the questions uses the same set of answers ( Agree . Disagree, Neutral ). Since so many of the possible answer sets repeat themselves I just put a method in the backing bean that returns an array of SelectItem with the choices in it.

This approach only works if the user only answers one question. If more than one question is answered (the user selects a radio button for more than one question) then a validation error occurs. Each of the <h:selectOneRadio> tags has a unique id. Also each of the <f:selectItem> tags have a unique id, even though they call back to the same backing method for the choices. In the backing bean method a new array is created and returned each time for the choices. I even tested creating a new method that returns an array of of SelectItem for the choices and had exactly the same issue.

If I change the code and put the <f:selectItem> tags directly inline in the code instead of calling the backing bean for an array of selectItems , then everything works like it should. I am very lost as to why I can not use the <f:selectItems> functionality more than once in a page. Here is a piece of the code:

<tr><td><h:outputText value="#{assessment.currentQuestionText}" /></td></tr>
                    <tr><td><h:selectOneRadio id="q3answers" value="#{assessment.q3}">
                                <f:selectItems id="q3list" value="#{assessment.currentQuestionAnswers}"/>
                            </h:selectOneRadio>
                            <br>
                        </td>
                    </tr>

                    <tr><td><h:outputText value="#{assessment.currentQuestionText}" /></td></tr>
                    <tr><td><h:selectOneRadio id="q4answers" value="#{assessment.q4}">
                                <f:selectItems id="q4list" value="#{assessment.currentQuestionAnswers}"/>
                            </h:selectOneRadio>
                            <br>
                        </td>
                    </tr>

You can see that each time I want a list of answers I call the currentQuestionAnswers method of the backing bean. The page displays correctly, and like stated above, the user can select an answer to one of the questions, but if the user answers both questions there is a validation error everytime. Any ideas? Help is greatly appreciated!
