Hi,
First of all let me apologise for the length of this post, I thought I
should include too much info rather than too little.
I'm using wicket-1.3.1, Spring 2.5.1 on JDK1.5 and Jetty6.1.6. My goal is
to define 1..n Panels in my Spring application context then access them from
within a test page using @SpringBean annotations.
applicationContext.xml contains:
<bean id="testPanel1" class="com.fastsearch.admomentum.server.TestPanel"
scope="prototype">
<constructor-arg value="testPanelOne"/>
</bean>
TestPage class is as follows:
public class TestPage extends WebPage {
@SpringBean(name="testPanel1")
private TestPanel testPanel1;
public TestPage() {
add(testPanel1);
}
}
And TestPanel class is as follows:
public class TestPanel extends Panel implements ITestPanel {
private TestForm form;
public TestPanel(String id) {
super(id);
form = new TestForm("testForm");
form.setTestFormField("oranges");
add(form);
}
private class TestForm extends Form {
private String testFormField;
public TestForm(String id) {
super(id);
add(new TextField("testFormField", new PropertyModel(this,
"testFormField")));
}
protected void onSubmit() {
PageParameters params = new PageParameters();
params.add("testFormField", testFormField);
}
public void setTestFormField(String testFormField) {
this.testFormField = testFormField;
}
}
}
So, the problem is that when I hit http://localhost:8080/ the
"add(testPanel1);" line in the constructor for TestPage causes the following
exception to be thrown:

-----------------------------------
Based on this stack trace I tried overriding onBeforeRender() in TestPanel
and changing it's scope to public ... just to see what would happen:
public void onBeforeRender() {
super.onBeforeRender();
}
but that then caused the following exception to be thrown which claims
"Something in the hierarchy of
WICKET_com.fastsearch.admomentum.server.test.TestPanel$$EnhancerByCGLIB$$11ed548f
has not called super.onBeforeRender() in the override of onBeforeRender()
method", which is clearly not the case.

-----------------------------------
Can anyone throw some light on what I'm doing wrong. I'm not tied to the
idea of the Panels being prototype beans however without it, immediately on
server startup, I get a "WicketRuntimeException: There is no application
attached to current thread main". Making them prototype seems to be the
only way for me to get my server to startup cleanly.
Thanks,
Tom.
