-----------------------------------
Assignee: Igor Vaynberg
Fix Version/s: 1.4.9
1.5-M1

> when used in a Class within the root package (i.e. it has no package
> declaration)
> --------------------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: WICKET-2856
> URL: https://issues.apache.org/jira/browse/WICKET-2856
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.7
> Reporter: Dirk Meuser
> Assignee: Igor Vaynberg
> Priority: Minor
> Fix For: 1.4.9, 1.5-M1
>
>
> Cause is the line
> String packageName = clazz.getPackage().getName();
> because Class.getPackage() [respectivly Package.getPackage(Class)] returns
> null if a class has no dot in its full qualifier.
> Example (from the Java Doc for org.apache.wicket.model.StringResourceModel):
> -------------------- CODE ------------------------
> import org.apache.wicket.markup.html.WebPage;
> import org.apache.wicket.markup.html.basic.Label;
> import org.apache.wicket.model.StringResourceModel;
> public class MyPage extends WebPage {
> public MyPage() {
> add(new Label("username", new StringResourceModel("label.username",
> this, null)));
> }
> }
> -------------------- CODE ------------------------
> If this class is in the root directory (no package declaration as above) a
> NullPointerException is thrown.
