[jboss-user] [JBoss Seam] - Target Unreachable with two entity instances?
Hi, I have a page that contains two forms, one for search and one for save/update. If I
use a single entity instance for both forms, everything works well enough, but the search
field is sync'd with the save/update field. If I try to have two entity instances
(one for the search form, one for the save/update form) I get a:
javax.el.PropertyNotFoundException: /lender.xhtml @22,71
value="#{searchLender.lenderCode}": Target Unreachable, identifier
'searchLender' resolved to null
LenderManagerAction:
@In
| private Lender searchLender;
|
| @In
| private Lender lender;
|
| @In
| private FacesMessages facesMessages;
|
| public String search()
| {
| Query query = entityManager.createNamedQuery(Lender.class.getSimpleName() +
".findByCode");
| query.setParameter("lenderCode", searchLender.getLenderCode());
| try {
| lender = (Lender)query.getSingleResult();
| } catch (NoResultException e) {
| logger.info(e.getMessage());
| facesMessages.add("Lender not found for code: " +
searchLender.getLenderCode());
| return null;
| }
| return PAGE_LENDER;
| }
|
lender.xhtml:
<h:panelGrid columns="2" rowClasses="prop"
columnClasses="name,value">
| <h:outputLabel for="searchLender">Lender
Code</h:outputLabel>
| <h:inputText value="#{searchLender.lenderCode}"
size="6"/>
| </h:panelGrid>
| <div class="actionButtons">
| <h:commandButton type="submit" value="Search"
action="#{lenderManager.search}"/>
| </div>
|
All I have to do to make this work is remove "searchLender" from the session
bean, and point the search form to the common "lender" entity. Is there a
problem with having two instances of the same entity type?
Thanks,
Jon
