Answer 1

The problem is with your
<h:commandButton immediate="true" value="Modifier" action="#{SelectBean.ok}"/>
The immediate attribute action method causes JSF to go directly to the render phase 'of the same view' by calling facesContext.renderResponse(), then the components will behave as they do for a validation failure - by displaying the value cached in the component rather than fetching data from the backing bean.
