Re: [mylyn-integrators] Querys in Mylyn 3.0

["Avin Ismail" <avin@xxxxxx>]

Ok. I found the RepositoryQuery class, it sounds like the right one. But I
found a more fundemental error, and that is Mylyn/eclipse doesn't connect
to my server. When I click to "Add Task Repository", I see my repository.
But when I click "next", nothing happens. I got a nullPointerException
with the following trace:

I followed the steps on
http://jvliet.blogspot.com/2007/02/creating-mylar-connector-plugin-for.html
just like I did with mylyn 2.0 and tried to make it work with mylyn 3.0.
Can somebody please tell me what did I miss?

Kind regards,
Avin
