Hi,
I'm trying to migrate a Eclipse 2.1 application to Eclipse 3.2. This
application includes a wizard to create new .scenario files (they
describe component models). The application builds fine, but when I run
it and select File->New->Other->Other->Scenario and double click on the
icon, I get:

The relevant Java source code would be something like:
(import statements omitted)
public class Smw extends Wizard implements INewWizard {
protected IStructuredSelection selection;
...
public class Smwnfcp extends WizardNewFileCreationPage {
public Smwnfcp(String pageId, IStructuredSelection selection) {
super(pageId, selection);
}
...
}
public void addPages() {
nfcp = new Smwnfcp("whatever", selection); /*
ScenarioModelWizard.java:303, generates exception here */
...
}
...
}
The applications build path does include org.eclipse.ui.ide, which
defines org.eclipse.ui.dialogs.WizardNewFileCreationPage
Any ideas?
Thanks,
Rene

"Magically" fixed by reorganizing the imports / build infrastructure.
