Bug 6891 Enclosing type checkbox doesn't appear in tab order in new class wizard
Build 20011211 In the new class wizard, the checkbox for enclosing type doesn't appear in the tab order. The JDT code doesn't seem to be doing any magic.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/TypePage.java
int nElements= elements.size();
			for (int i= 0; i < nElements; i++) {
				String intfname= (String)elements.get(i);
				try {
					IType type= JavaModelUtil.findType(root.getJavaProject(), intfname);
					if (type == null) {
						status.setWarning(NewWizardMessages.getFormattedString("TypePage.warning.InterfaceNotExists", intfname)); 
						return status;
					} else {
						if (type.isClass()) {
							status.setWarning(NewWizardMessages.getFormattedString("TypePage.warning.InterfaceIsNotInterface", intfname)); 
							return status;
						}
						if (!JavaModelUtil.isVisible(type, getPackageFragment())) {
							status.setWarning(NewWizardMessages.getFormattedString("TypePage.warning.InterfaceIsNotVisible", intfname)); 
							return status;
						}
					}
				} catch (JavaModelException e) {
					JavaPlugin.log(e.getStatus());
					
				}					
			}				
		}
		return status;
	}
