Comment 2 Milos Kleint 2014-02-20 07:01:51 UTC

very weird. apparently
prj.getLookup().lookup(LogicalViewProvider.class); returned null which is close to impossible with maven projects (LVP is supposed to be always in the project lookup)

Integrated into 'main-silver', will be available in build *201403130001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

likely related to issue 243446 and issue 243427

Comment 6 Milos Kleint 2014-04-07 06:55:03 UTC

jtulach, just fyi that something weird started happening with (maven) project lookup starting mid february. Items that should always be in the lookup are no longer there, random and rare. could it be related to some generic lookup changes? any other similar issues in other areas?
