Dynamic Creation of Template

Question

Hi, I am creating the survey part using JSF as front end, basically survey has to create dynamic content like radio button,
check box,text area etc., I am able to do this and also sucess in displaying , so what I did for displaying purpose
I used the panel grid for each question, I used Datatable to get the list of survey questions from backend and I have render to check if it is radio button goes to this panel, if it is check box goes to this panel,and so on.,
it displaying good, but when I capture results It came up with last selected value only.,
example If i have three radio button panels , I am getting only one, I know becuase I am selecting only one value, so my quesitons is how can I select all three panel
<h:dataTable var="surveyList" value="#{questionBean.listItems}"
                                   width="100%" styleClass="centerall">
                                   <h:column>
                                        <h:panelGrid columns="1" rendered="#{surveyList.dropType}">
                                             <h:graphicImage url="/images/bar2.gif" />
                                             <h:outputLabel value="#{surveyList.questionDesc}"
                                                  styleClass="TTStableheader" />
                                             <h:selectOneMenu value="#{radioQuestions.selectedType}"
                                                  styleClass="selectOneMenu" tabindex="50">
                                                  <f:selectItems value="#{surveyList.selectedList}" />

Hi Heiko,
You have done everything correctly....except for 1 line
in the code...
Replace the following line in your code:
actionAddElement.getActionParameters().addParameter("featureIndex", new Integer(i).toString());
Replace the above line with this code:
button.mappingOfOnAction().addParameter("featureIndex",i);
Actually in your code, you are not associating the parameter with the button...
Note that addParameter(...) comes with two signatures: addParameter(String param, String value) and addParameter(String param, int value). You can use any of them based on yuor need.
Hope it helps,
Thanks and Regards,
