Comment 1 Ralf Sternberg

2012-05-23 13:30:50 EDT

The introduction of the additional method IExampleConfiguration#configure( Application ) in commit f24b9dbe0e5d926c1a489cb115e6bd507cfc69d3 was a failed attempt to allow contributions to register resources. This does not work because contributing bundles are not necessarily started when the application starts. We have to find another method of letting contributions register their resources.

Fixed by revoking this change with commit 67a55c73e6762b94cf03ca02d6731a1c52dd35dd.

I'd suggest to pick this commit also for 1.5.

+1 The removed code actually did nothing and I think that it is safe to commit it in 1.5.

Comment 3 Ralf Sternberg

Fixed in 1.5 with commit d8874189a23de8b6cae3326860665d7f57bcd797
