What steps will reproduce the problem?
1. In the zk spring essentials example (from
http://zkbooks.googlecode.com/svn/trunk/zkspringessentials/zkspringcoresec/zkspr
ingessentials.war),
let the greeting be shown as Label inside a Div.
modified org.zkoss.zkspringessentials.controller.GreetingCtrl:
@org.springframework.stereotype.Component("greetingCtrl")
@Scope("prototype")
public class GreetingCtrl extends GenericSpringComposer {
@Autowired private Textbox name;
@Autowired private Button greetBtn;
@Autowired private Div myDiv;
public void doAfterCompose(Component comp) throws Exception {
super.doAfterCompose(comp);
}
@EventHandler("greetBtn.onClick")
public void showGreeting(Event evt) throws WrongValueException, InterruptedException {
myDiv.getChildren().clear();
new Label("Hello " + name.getValue() + "!").setParent(myDiv);
}
}
modified autowirezkcomp.zul:
<?xml version="1.0" encoding="UTF-8"?>
<?variable-resolver class="org.zkoss.zkplus.spring.DelegatingVariableResolver"?>
<window title="Autowire ZK Components Example" border="normal" height="100px"
width="400px" apply="${greetingCtrl}">
<label value="Name:"></label>
<textbox id="name" />
<button id="greetBtn" label="Greet!" />
<div id="myDiv"/>
</window>
2. Open "/autowirezkcomp.zul" and click several times on on the "Greet!" button.
What is the expected output? What do you see instead?
myDiv.getChildren().clear(); does not work so you will see "Hello X!Hello Y!"
and get a java.util.ConcurrentModificationException at the third time.
What version of the product are you using? On what operating system?
zkspring-3.0, zk-5.0.6, apache-tomcat-7
