What steps will reproduce the problem?
1. In the zk spring essentials example (from http://zkbooks.googlecode.com/svn/trunk/zkspringessentials/zkspringcoresec/zkspringessentials.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
