Description Jean-Michel Lemieux

2010-08-27 15:01:19 EDT

When I install Eclipse 3.6, I am able to import plugins & fragments from my target platform using the Import --> Plugins and Fragments dialog.  After installing our product using our new P2 repo, this dialog is completely broken.  The next button brings me to a blank pane, and if I click it again I get the expected dialog for specifying how/where to import plugins but none of the buttons are enabled.

I'm also unable to import any plugins from the Plugins view.  Right clicking on a plugin and selecting Import results in an NPE (see attached screenshot).

I can provide access to our p2 update site if needed.

Eclipse (32-bit or 64-bit)
Version: 3.6.0
Build id: I20100608-0911

There are two related crashes in my log file.

Comment 1 Remy Suen

Should be fixed by bug 313952 and bug 320123.

Comment 2 Ankur Sharma

2010-08-30 02:29:11 EDT

I agree with Remy and most likely we have this problem already fixed. Closing as dupe of Bug 313952.
Please do reopen if you find the problem persists in latest I builds.
