Hi,
I am trying to use wicket:extend mechanism to share common functionality between pages and it seem to work only with one level of hierarchy. When I add another level, I get error (pasted below). Am I doing something incorrectly?
Here is code to reproduce the behavior:
Base.html:
<html>
<body>
<span wicket:id="baseLabel">base label</span>
<wicket:child/>
</body>
</html>
Sub.html:
<html>
<body>
<wicket:extend>
<span wicket:id="subLabel">sub label</span>
</wicket:extend>
<wicket:child/>
</body>
</html>
SubSub.html:
<html>
<body>
<wicket:extend>
<p>Sub sub</p>
</wicket:extend>
</body>
</html>
Base.java:
package com.aspectivity.wicket.bugs;
import wicket.markup.html.WebPage;
import wicket.markup.html.basic.Label;
public class Base extends WebPage {
public Base() {
add(new Label("baseLabel", "This is label added by base"));
}
}
Sub.java:
package com.aspectivity.wicket.bugs;
import wicket.markup.html.basic.Label;
public class Sub extends Base {
public Sub() {
add(new Label("subLabel", "This is label added by sub"));
}
}
SubSub.java:
package com.aspectivity.wicket.bugs;
public class SubSub extends Sub {
}
With this code, I get the following exception:
wicket.markup.MarkupNotFoundException: Markup of type 'html' for component 'com.aspectivity.wicket.bugs.SubSub' not found. Enable debug messages for wicket.util.resource.Resource to get a list of all filenames tried:
