> </t:selectManyCheckbox>
> <t:commandButton value="submitTargetPages" style="width:100px" immediate="true" onclick="submit()" forceId="true" actionListener="#{test_scope.targetPagesSelectedAction}" />
> In the bean:
> ----------------
> public void targetPagesSelectedAction(ActionEvent event)
> {
> Object[] xx = htmlSelect.getSelectedValues();
> FacesContext.getCurrentInstance().renderResponse();
> }
> Causes the following exception:
