nice exampe. very easy to understand a recreate problem. you propably need to reset the validationstatus of the form somehow. primefaces has some components for reset, but i havnt played around with them enough to answer your question. — Aksel Willgert, Dec 03 '12 at 15:24
Your examples run fine (copy-paste, no edits) here in my environment, however I am using primefaces 3.3.1 Maybe updating your primefaces version can fix it. — Mindwin Remember Monica, Dec 03 '12 at 15:32
open the console or firebug, see if the page is making the ajax calls after the submit. — Mindwin Remember Monica, Dec 03 '12 at 15:35

Looks like you have run into this problem:

How can I populate a text field using PrimeFaces AJAX after validation errors occur?

Adding the following to faces-config.xml together with OmniFaces library made your select-one-menu update the inputField correctly

<lifecycle>
    <phase-listener>org.omnifaces.eventlistener.ResetInputAjaxActionListener</phase-listener>
</lifecycle>

If you dont want to do it for all your components, OmniFaces has a showcase how to do it per component: http://showcase.omnifaces.org/eventlisteners/ResetInputAjaxActionListener
