Description Rohan Ranade 2007-09-15 09:45:15 UTC 
When creating a new project instance of my custom project type in NetBeans 6.0 (NBMs attached), NetBeans throws an NPE.
The stack trace is given below. It seems to be a problem in the Profiler's ProjectUtilities class. Disabling the
profiler module removes these exceptions. The same code used to work fine in NetBeans 5.5.1.

Comment 2 Rohan Ranade 2007-09-15 09:52:50 UTC 
Lookup contents of the Project:

private Lookup createLookup(AuxiliaryConfiguration aux) {
        return Lookups.fixed(new Object[]{
            new Info(), // ProjectInformation
            aux, 
            helper.createCacheDirectoryProvider(), 
            new ProjectXmlSavedHookImpl(), 
            new ProjectOpenedHookImpl(), 
            new BasicProjectSources(this.helper, evaluator(), getComponentRoots(), getPlanRoots(), null), 
            new RecommendedTemplatesImpl(), 
            new BasicProjectLogicalViewProvider(this, this.helper, evaluator()), 
            metaProvider, 
            this});
    }

Please evaluate, thanks.
Comment 4 J Bachorik 2007-09-17 12:48:46 UTC 
this was caused by the lack of check for NP when calling operations on a lookup result
it is now fixed
