ClassCastException when loading org.eclipse.jface

Postby tv » Tue Jul 18, 2006 10:42 am

Hi folks,

I have FastTrack 0.9.0 installed on Eclipse 3.1.2 When I have conflicted resources in my projects, I get the following exception:

What happened? And how do I get rid of it?

Hello,
thank you for posting your error report of our bug. It seems that you have conflicts at least on file shared with non subversive svn provider. This will be fixed in next release of Fast Track. If i am wrong, please provide me more information how to reproduce this error.
Best regards,

Still problems

I had Subclipse installed which I removed because of your comment but the problem persists. It usually happens when a merge from a branch is performed and I try to navigate in the "Team Synchronize" tree view. One click on a conflicted resource creates that error message.

On another installation the error message is slightly different:

A clean install of Eclipse and FastTrack shows the same problem.
