Notice: Due to upgrading issues dealing with GEF we have taken down the MyEclipse upgrade site until further notice. If you have upgraded from MyEclipse 3.8 Beta 1 to 3.8 Beta 2 through the update site, please follow the fix instructions below.

Quickfix Installation:

• Download the file: http://www.myeclipseide.com/products/eworkbench/quickfixes/UpdateSite_3.8Beta2.zip
• Unzip the file into your ‘eclipse’ directory under your ‘MyEclipse’ directory
  (e.g. if ME is installed to C:\Program Files\MyEclipse 3.8, then this file must be unzipped into C:\Program Files\MyEclipse 3.8\eclipse. Also you should get “overwrite” warnings when unzipping the file, say “Yes” or “All” to them. If you do not get “overwrite” warnings, double check that you didn’t unzip the file to the wrong location.
• Restart Eclipse

Quickfix Details:
The quickfix replaces the GEF and Draw2D plugins with the 3.0 Final releases. There have been a number of reported problems when upgrading because people have had non-final releases of GEF and Draw2D in their Eclipse plugins directory, conflicting with MyEclipse’s requirement for the final releases of these libraries.

If you did a fresh install from the Update Site or used the manual installer or one of the double-click installers, you do not need to apply this quickfix.

As an added note, these GEF problems manifest as errors while trying to open the Struts editor and exceptions in the log file pertaining to the org.eclipse.gef package.

I am still getting problems with this when opening the struts config editor, has this been fixed?

We need just a tad more information from you to help here… short answer is “yes, you are reading the post that fixes the problem”, the long answer is: “assuming your setup is sane and you followed all the directions correctly, then there is likely something ELSE going on…”

Can you please post all the information we request in the [URL=http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-393.html]Posting Guidelines[/URL] thread at the top of this forum? That will give us some context so that we can determine if this is an installation issue, a configuration problem, or a bug. Thanks.

help!!

and thanks in advance

[Riyad Kalla]

pdscott,
Do me a favor and look in your Eclipse\plugins directory for a directory called “org.eclipse.gef_3.0.0”, do you have one? If so, shut down Eclipse, move that directory to your desktop or someplace out of the plugins dir, and start Eclipse again. Did the problem go away?

[pdscott]

got it sorted. Sorry, reinstalled Eclipse, followed by the beta 1, then uninstalled beta 1 and reinstalled beta 2, and it worked.

[Riyad Kalla]

Glad its working.
