Re: WOLips NPE whenever opening a component?

Hi,

First, you should send your request to the =
[email protected] list, a lot of people left the omnigroup =
mailing list years ago.

As for Eclipse, don't use 4.2. Follow those instructions instead:

http://wiki.wocommunity.org/display/documentation/Project+Wonder+Installat=
ion

Eclipse 3.7 or 3.8 is the way to go. 4.2 is buggy.

something like that, so as to be able to check which of the upgrades =

seriously outdated -- the WOLips blog has its newest item of 2009, etc. =
The installation instructions just say "Head over to the Eclipse =

Eclipse version was really the latest one at the time somebody wrote =
that...
