[JBoss Seam] - EL and an emelemtn out of a LinkedHashSet
by tony.herstell＠gmail.com
| <!-- Keywords -->
| <tr>
| <td>
| <h:outputText value="#{messages.no_keywords}" rendered="#{advertisingCampaign.keywords == null}"/>
| <h:dataTable id="resultantKeywordsTable" var="eachResultantKeyword" value="#{advertisingCampaign.keywords}"
| rendered="#{advertisingCampaign.keywords != null}">
| <h:column>
| <f:facet name="header">
| <h:outputText value="#{messages.label_keywords}" />
| </f:facet>
| <h:outputText value="eachResultantKeyword.keyword"/>
| </h:column>
| </h:dataTable>
| </td>
| </tr>
|
this
<h:outputText value="eachResultantKeyword.keyword"/>
should be
<h:outputText value="#{eachResultantKeyword.keyword}"/>
but this does not work:
| javax.faces.el.PropertyNotFoundException: /WEB-INF/pages/advertisingCampaignWizard/sideProgressMenu.xhtml @316,71 value="#{eachResultantKeyword.keyword}": Bean: java.util.LinkedHashSet, property: keyword
| at com.sun.facelets.el.LegacyValueBinding.getValue(LegacyValueBinding.java:58)
|
Any suggestions as it does exist...?

[JBoss Seam] - Help: problem with EntityHome
by qzhengyy
Hi,
I am having problem using EntityHome. I have an entity class Foo, follow the Seam documentation in Section 10.2 I define a FooHome class
| public FooHome extends EntityHome<Foo> {
| }
|
First I get null pointer exception because getEntityManager() returns null. I solve this problem by injecting an entity manager. Now when I call persist() I get the following exception:

For debugging purpose, I redefined persist method in FooHome and cut and paste the code from EntityHome.persist. The null pointer exception is caused by PersistenceProvide.instance() returns null. Am I missing something? I thought when I use EntityHome I don't need to anything in the XML configuration file.
Thanks in advance.
Qing
