It's duplicate of issue 92317. Thanks for your report. *** This issue has been marked as a duplicate of 92317 *** Node node = (Node) activatedNodes[0].getLookup().lookup(Object.class);
Lookup theLookup = node.getLookup();
System.out.println("Dumping Lookup...");
InstanceCookie ic = (InstanceCookie) theLookup.lookup(InstanceCookie.class);
if (DogBean.class.equals(ic.instanceClass())) {
DogBean dog1 = (DogBean) ic.instanceCreate();
System.out.println(" Dog Name => " + dog1.getName());
}
->
void m() {
try {
Node[] activatedNodes = null;
Node node = (Node) activatedNodes[0].getLookup().lookup(Object.class);
Lookup theLookup = node.getLookup();
System.out.println("Dumping Lookup...");
InstanceCookie ic = theLookup.lookup(InstanceCookie.class);
if (DogBean.class.equals(ic.instanceClass())) {
DogBean dog1 = (DogBean) ic.instanceCreate();
System.out.println(" Dog Name => " + dog1.getName());
}
} catch (IOException ex) {
Exceptions.printStackTrace(ex);
} catch (ClassNotFoundException ex) {
Exceptions.printStackTrace(ex);
}
}
Array is duplicated, but it is another problem, will be reported separately.

Using NetBeans 6.0 milestone 7 on Windows XP under Java 6, I wrote the following code inside the performAction of CookieAction class: Node node = (Node) activatedNodes[0].getLookup().lookup(Object.class); Lookup theLookup = node.getLookup(); System.out.println("Dumping Lookup..."); InstanceCookie ic = (InstanceCookie) theLookup.lookup(InstanceCookie.class); if (DogBean.class.equals(ic.instanceClass())) { DogBean dog1 = (DogBean) ic.instanceCreate(); System.out.println(" Dog Name => " + dog1.getName()); } This code can throw can IOException, so I clicked the "lightbulb" icon to fix the code by surrounding the code with a try/catch block. When I do this, the code switches to using unnecessary fully-qualified classnames: try { org.openide.nodes.Node node = (org.openide.nodes.Node) activatedNodes[0].getLookup().lookup(java.lang.Object.class); org.openide.util.Lookup theLookup = node.getLookup(); java.lang.System.out.println("Dumping Lookup..."); org.openide.cookies.InstanceCookie ic = (org.openide.cookies.InstanceCookie) theLookup.lookup(org.openide.cookies.InstanceCookie.class); if (com.example.beannodeexample.DogBean.class.equals(ic.instanceClass())) { com.example.beannodeexample.DogBean dog1 = (com.example.beannodeexample.DogBean) ic.instanceCreate(); java.lang.System.out.println(" Dog Name => " + dog1.getName()); } } catch (IOException ex) { Exceptions.printStackTrace(ex); } catch (ClassNotFoundException ex) { Exceptions.printStackTrace(ex); } I did something similar last week and, instead of doing that, it actually deleted my code entirely. Unfortunately, I was interrupted before I could log the exact circumstances.
