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!
