[News.eclipse.technology.mylar] Re: Upgrade causes error

[Jörg Thönnes <Joerg.Thoennes@xxxxxxxx>]

Hi Stefan,

this is bug 180518. Mik and Rob built a dev release yesterday evening to verify that they fixed bug.

I downloaded this release since I was experiencing the errror you describe. Now this works well for 
me. Checking the Mylar update site at

http://download.eclipse.org/technology/mylar/update-site/dev/e3.2/

the site.xml now contains

version="2.0.0.v20070403-1300"

for the 2.0M2 build. Please update again and reopen the bug if it does not fix your problem.

Cheers, Jörg
