WOLips NPE whenever opening a component?

[OC]

Hello there,

after a comparatively long time I've got back to my WO projects; meantime I've updated Eclipse and plugins more than once, so alas I can't quite point out which of the steps was the culprit.

Nevertheless, now whenever I try to open any component, _LOTS_ of NPEs occur, like this:

!ENTRY org.eclipse.e4.ui.workbench 4 0 2013-02-07 02:47:24.469

...

and so forth, hundreds of them.

Here's a list of my installed software versions:

Eclipse IDE for Java Developers 1.5.1.20121004-1506 epp.package.java null
Groovy Compiler 2.0 Feature 2.8.0.xx-20130205-1700-e42 org.codehaus.groovy20.feature.feature.group Codehaus.org
Groovy-Eclipse Feature 2.8.0.xx-20130205-1700-e42 org.codehaus.groovy.eclipse.feature.feature.group Codehaus.org
JDT Core patch for Groovy-Eclipse plugin 2.8.0.xx-20130205-1700-e42 org.codehaus.groovy.jdt.patch.feature.group Codehaus.org
WOLips 4.2.20130127.7 org.objectstyle.wolips.feature.feature.group objectstyle.org
WOLips Goodies 4.2.20130127.7 org.objectstyle.wolips.goodies.feature.feature.group objectstyle.org
WOLips Groovy Support 4.2.20130127.7 org.objectstyle.wolips.groovy.feature.feature.group objectstyle.org

I've tried to find some kind of WOLips/Eclipse-compatibility list or something like that, so as to be able to check which of the upgrades might have been the culprit; but in vain: whatever I found on http://wiki.wocommunity.org/display/WOL/Home and elsewhere seems seriously outdated -- the WOLips blog has its newest item of 2009, etc. The installation instructions just say "Head over to the Eclipse Foundation and download the latest version of Eclipse suitable for your OS X version", which is exactly what I did, but I do wonder which Eclipse version was really the latest one at the time somebody wrote that...

Anyway, can perhaps anybody recognize this behaviour and can help me to work around it? Whilst I _can_ edit my components using TextEdit, it is sort of inconvenient... and trying to go backward re-installing older versions of Eclipse and the individual features does not look like a good option either :(

Thanks a very big lot,
OC

Hi,

First, you should send your request to the webobjects-***@lists.apple.com 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+Installation

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

Seriously? I'm using 4.2 and it doesn't look so buggy to me… Except for the ugly UI works just fine!

Q came back to 3.8 for WOLips, and since he's the main WOLips guy, don't expect bug fixes for 4.2 for now.
