Need help with using ValueChangeEvent and SEAM
I have a simple application that has a radio box and displays the value of the radio box to the screen. Everything seems to be working except when I browse away from that page and then browse back I get and Exception.
<h:form>
<h:selectOneRadio
value="#{advancedSearch.currentType}"
valueChangeListener="#{advancedSearch.typeSelected}"
immediate="true"
onclick="submit()"
>
<f:selectItems value="#{searchTypeList}" />
</h:selectOneRadio>
<h:outputText value="#{advancedSearch.currentType.label}"/>
</h:form>and the code is
@Stateless()
@Name("advancedSearch")
public class AdvancedSearchBean implements AdvancedSearchLocal {
private SelectItem currentType;
@Out
private List<SelectItem> searchTypeList;
@In
private FacesContext facesContext;
@Factory("searchTypeList")
public void loadList() {
setSearchTypeList(new ArrayList());
getSearchTypeList().add(new SelectItem("1","1"));
getSearchTypeList().add(new SelectItem("2","2"));
}
public void typeSelected(ValueChangeEvent event) {
String value = (String) event.getNewValue();
if ("1".equals(value)) {
currentType = getSearchTypeList().get(0);
} else if ("2".equals(value)) {
currentType = getSearchTypeList().get(1);
}
//Not sure if this line is needed, it work without it
facesContext.renderResponse();
}
public SelectItem getCurrentType() {
return currentType;
}
public void setCurrentType(SelectItem currentType) {
this.currentType = currentType;
}
public List<SelectItem> getSearchTypeList() {
return searchTypeList;
}
public void setSearchTypeList(List<SelectItem> searchTypeList) {
this.searchTypeList = searchTypeList;
}
}
the exception is
