Hi list,
After upgrading to Wicket 1.2, wicket tests for my project don't work
anymore. Testing a page that is initialized using a custom constructor
causes a WicketRuntimeException:
wicket.WicketRuntimeException: Internal error cloning object. Make sure
all dependent objects implement Serializable. Class:
wicket.util.tester.DummyHomePage
at
wicket.protocol.http.HttpSessionStore.setAttribute(HttpSessionStore.java:62)
[... bits of stacktrace omitted for brevity ...]
Caused by: java.io.NotSerializableException: com.example.MyPageTest$1
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1075)
at
java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1369)
[... rest of stacktrace omitted for brevity ...]
I created the initialized page with an anonymous ITestPageSource, as per
the WicketTester javadocs.
Consider the following example code that causes the error:
MyPage.html:
- - - - - - - - - - - - - - - - - - - - - - - - - -
<html xmlns:wicket="http://wicket.sourceforge.net/";>
<head><title>bla</title></head>
<body>
<h1><span wicket:id="title">(title)</span></h1>
</body>
</html>
- - - - - - - - - - - - - - - - - - - - - - - - - -
MyPage.java:
- - - - - - - - - - - - - - - - - - - - - - - - - -
package com.example;
import wicket.markup.html.WebPage;
import wicket.markup.html.basic.Label;
public class MyPage extends WebPage {
public MyPage() {
this("empty");
}
public MyPage(String title) {
add(new Label("title",title));
}
}
- - - - - - - - - - - - - - - - - - - - - - - - - -
and finally, MyPageTest.java:
- - - - - - - - - - - - - - - - - - - - - - - - - -
package com.example;
import junit.framework.TestCase;
import wicket.Page;
import wicket.util.tester.ITestPageSource;
import wicket.util.tester.WicketTester;
public class MyPageTest extends TestCase {
public void testRenderMyPage() {
WicketTester tester = new WicketTester();
// the following statement throws the exception:
tester.startPage(new ITestPageSource() {
public Page getTestPage() {
return new MyPage("hello world");
}
});
}
}
- - - - - - - - - - - - - - - - - - - - - - - - - -
What's happening here? Most of my pages use custom constructors to
initialize the page, and every test method that use these cause the
error. What can I do about it?
cheers,
Gert
