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?
