dataList with radio buttons

[Richard Wallace <rw...@thewallacepack.net>]

Hello,

I've got a dataList bound to a list of values in the backing bean as such:

                <x:dataList id="questionList" layout="simple" 
value="#{assessmentHandler.currentPage.questions}" var="question">
                    <h:outputText value="#{question.questionNo}. 
#{question.text}" />
                    <f:verbatim><br /></f:verbatim>
                    <h:selectOneRadio id="choices" required="true" 
value="#{assessmentHandler.responses[question.questionNo - 1].score}">
                        <f:selectItem id="oftenChoice" 
itemValue="#{assessmentHandler.oftenScore}" 
itemLabel="#{labels.oftenLabel}" />
                        <f:selectItem id="sometimesChoice" 
itemValue="#{assessmentHandler.sometimesScore}" 
itemLabel="#{labels.sometimesLabel}" />
                        <f:selectItem id="seldomChoice" 
itemValue="#{assessmentHandler.seldomScore}" 
itemLabel="#{labels.seldomLabel}" />
                    </h:selectOneRadio>
                </x:dataList>

The assessmentHandler has the method getResponses() which returns a List 
of Response objects.  The Response objects has a getter/setter for the 
score attribute.  However, when I click the command button to advance to 
the next page or to finish the questioning the Response objects score 
values in the backing list is not updated with the value of the select 
item.  The required="true" attribute also seems to be ignored, because I 
can safely advance without any errors.  Is this not the right way to do 
something like this? 

I've looked at the list and the only alternative is to use Bruno 
Aranda's valueChangeListener solution from the "is it possible to edit 
dynamic Tabular data?" thread.  But, as was stated in that thread, it 
seems like the way I'm doing it should work to update the data model.  I 
don't need to implement a setResponses() method do I?  The setScore() 
method on the actual Response object should be enough, shouldn't it be?  
I'm sure I don't need to use the preserveDataModel attribute or an 
<x:saveState /> element.  So what's missing?

Thanks,
Rich

Weird, I changed from <x:dataList> to <x:dataTable> and validation and 
updating the data model works as it should.  It's too bad cause I'd 
rather not have to use a table for page layout.  Using the list would 
allow my designer to use <div> tags.  Is this a bug or something that 
the <x:dataList> isn't meant to be used for?

Thanks,
Rich

Was immediate="true" in the dataTable element?

I simply meant that if I clicked on a command button, such as "Next" or 
"Finish" that MyFaces happily accepts the input as even if nothing is 
filled in on the form, completely bypassing the validation.  But, it 
doesn't update the data model.  At least, it doesn't update the data 
model if <x:dataList> is used.  It does if <h:dataTable> is used.  If 
dataTable is used everything works as it should.

Can you please elaborate on "The required="true" attribute also seems to 
be ignored, because I 
can safely advance without any errors."?
