[JBoss Seam] - HelloWorld-Ajax with Facelets
by hispeedsurfer
Hello,
running the helloworld4 example with .jsp from JBoss Seam Book was successful.
Here the code:
ManagerAction.java
int MAX_RESULTS_RETURNED = 10;
| String [] popularNames = new String [] {
| "Gavin King", "Thomas Heute", "Michael Yuan",
| "Norman Richards", "Bill Burke", "Marc Fleury"
| };
| public void suggestName (FacesContext context,
| String partialName, CompletionResult result) {
|
| System.out.println("Auto Complete method is called");
|
| int totalNum = 0;
| if (partialName.length() > 0) {
| for (int i=0; i<popularNames.length; i++) {
| if (popularNames.toLowerCase().indexOf(partialName.toLowerCase())!=-1
| && totalNum < MAX_RESULTS_RETURNED) {
|
| result.addItem(popularNames);
| totalNum++;
| }
| }
| } else {
| for (int i=0; i<MAX_RESULTS_RETURNED &&
| i<popularNames.length; i++) {
| result.addItem(popularNames);
| }
| }
|
| }
hello.jsp
<h:form>
|
| <h:panelGrid columns="2">
| <h:outputText value="Your Name" />
| <h:panelGroup>
| <ui:autoComplete
| size="15" id="name"
| completionMethod="#{manager.suggestName}"
| value="#{greeter.name}"
| required="false" />
| <h:message for="name" />
| </h:panelGroup>
Now, when I use Facelets for a similar example with same Bean-Code I receive the Error:
ELException: /hello2.xhtml: Bean: org.jboss.seam.intercept.Proxy$$EnhancerByCGLIB$$73f8c9e7, property: suggestName

The suggestName method is declared in Hello.java interface and HelloBean.java

[Persistence, JBoss/CMP, Hibernate, Database] - Hibernate, fetch-join + order by order problem
by virgo47
Hello
I have normal master-detail table pair where master table has mapping like this (important snippets):
<hibernate-mapping>
| <class name="BE" table="be">
| ...
| <property name="stopTimestamp" type="java.util.Date" column="STOP_TS"
| not-null="false"/>
|
| ...
| <bag name="analysis" cascade="all" order-by="start_ts">
| <key column="be_id"/>
| <one-to-many class="BEAnalysis"/>
| </bag>
| ...
| </class>
| </hibernate-mapping>
So I have analyzes ordered by their start_ts column. Now we need process big portion of BEs along with their analysis and we used fetch join in order to do it quickly (lazy load was unacceptably slow - too many selects).
Code for listing those BE with analysis.
Criteria criteria = session.createCriteria(BE.class);
| ...
| criteria.addOrder(Order.asc("stopTimestamp"));
| criteria.setFetchMode("analysis", FetchMode.JOIN);
| return (Collection<BE>) criteria.list();
And now tail of the generated SQL:
... order by analysis2_.start_ts, this_.STOP_TS asc
(this_ is be table of course)
Problem is that I need to order by stop_ts first (be order is much more important, than comes the order of related analysis). What's the cure for this? Thanks for hint
Virgo
