I have the following snippet in a page:

<s:decorate id="creditCardTypeDecoration" template="/layout/edit.xhtml">
 <ui:define name="label">Credit Card Type:</ui:define>
 <h:selectOneMenu value="#{customerHome.instance.creditCardType}" required="true">
 <s:selectItems value="#{userDAO.creditCardTypeList}" var="ccType" label="#{ccType.creditCardType}" noSelectionLabel="Select Type" />
 <s:convertEntity />
 </h:selectOneMenu>
 </s:decorate>

The userDAO has the following method:

public List<CreditCardType> getCreditCardTypeList() throws CacheException
 {
 List<CreditCardType> creditCardType = (ArrayList<CreditCardType>)pojoCache.get( "reference", "creditCardTypeList" );

 if ( creditCardType == null )
 {
 creditCardType = entityManager.createQuery( "from CreditCardType creditCardType" ).getResultList();
 pojoCache.put( "reference", "creditCardTypeList", creditCardType );
 }

 return creditCardType;
 }

When the data comes from the cache in the validation of the form I get a value is not valid error.

When I use the following method all is well - however, a database call is made with all of the lookups. I have this pattern happening many times throughout the site and it is very expensive.

public List<CreditCardType> getCreditCardTypeList() throws CacheException
 {
 return entityManager.createQuery( "from CreditCardType creditCardType" ).getResultList();
 }

Any help will be appreciated.

As an FYI I have tried to get this to work using the EJB3EntityTreeCache with no luck. I have the cache configured correctly with no errors, but it still goes to the database every time. Has anyone figured out how to get caching to work with a seam managed entity manager?
