here is my groovy file
package gov.hhs.acf.web.util;
import java.util.ArrayList;
import java.util.List;
import org.apache.wicket.Component;
import org.apache.wicket.MarkupContainer;
import org.apache.wicket.markup.IMarkupResourceStreamProvider;
import org.apache.wicket.markup.html.link.Link;
import org.apache.wicket.markup.html.panel.Panel;
import org.apache.wicket.util.resource.IResourceStream;
import org.apache.wicket.util.resource.StringResourceStream;
class UserMenuItems implements MenuItems {
List<Component> components ;
void myInit(){
components= new ArrayList<Component>();
components.add (new OMBCircularPanel());
components.add (new SendComments());
}
@Override
public List<Component> getComponents() {
myInit();
return components;
}
private abstract class CustomPanel extends Panel implements
IMarkupResourceStreamProvider{
public CustomPanel() {
super(MenuItems.menuItemId);
}
public IResourceStream getMarkupResourceStream(MarkupContainer
container,Class<?> containerClass){
return new StringResourceStream(getMarkUp());
}
protected abstract String getMarkUp();
}
private class OMBCircularPanel extends CustomPanel {
public OMBCircularPanel() {
super();
}
@Override
protected String getMarkUp() {
return """
<wicket:panel>
http://www.whitehouse.gov/sites/default/files/omb/assets/a133/a133_revised_2007.pdf
A-133 OMB Circular
</wicket:panel>
""";
}
}
private class SendComments extends CustomPanel {
public SendComments() {
super();
}
@Override
protected String getMarkUp() {
return """
<wicket:panel>
mailto:[email protected] Send
Comments
</wicket:panel>
""";
}
}
}
this is a simple class creating some wicket panels .
When I call getComponents , I get this exception
Caused by: java.lang.ArrayIndexOutOfBoundsException: 0

please somebody help me what is the error referring to, I donot have any
method called init I tried debugger and noticed the exception is thrown
before it reaches super class constructor .
the same code when I replace """.....""" with normal java string works well
, please tell me what is going wrong , I want this as groovy becasue I
want to dynamically load MenuItems and change them without restarting the
server
