I can’t get debug view to work on OSX using the latest MyEclipseIDE. I tried both 3.8.1 and 3.8.2 on Eclipse 3.0 and 3.0.1. The debug view works fine w/out MyEclipse, but after it is installed an error message pops up when I try to open the debug view which says ‘An error occurred while restoring the view: org.eclipse debug.ui.DebugView’.

I am working with completely fresh installs/workspaces.

Please help

Saxon,
Is there any exception trace in your log file (workspace dir\.metadata\.log) that could be related to this? Try and shut down Eclipse, clear your log file, fire it up and try and switch to your debug perspective… then copy the exception in here for us ot look at.

Here’s the stack trace:

Thank you, I’ll ask our Mac OSX guy to have a look.

[Scott Anderson]

‘An error occurred while restoring the view: org.eclipse debug.ui.DebugView’.

That’s not necessarily problematic, as long as you can then open the debug perspective manually and the view reconstitutes itself. However, the ClassNotFoundException *does* look like an installation problem. Are you running on OS/X 10.3? Eclipse will not run consistently on 10.2 and requires 10.3. Also, before installing MyEclipse, please close all the editors and perspectives in your existing workspace, shutdown, install MyEclipse, and then launch it with a *new* workspace. See if it looks OK, and if it does, shut it down and then relaunch with your existing workspace. I’d definately recommend a clean install of 3.0.1 and ME 3.8.2, i nparallel with your current one, to get you going as quickly as possible.

[sdaubin]

I’m running 10.3. Here’s what I did:

1) Untarred Eclipse 3.0. Opened it with a new workspace. Debug view worked fine.

2) Closed Eclipse. Installed MyEclipse 3.8.1. Opened it with the workspace that was just created. Got the above exception. Reset the debug perspective. Same exception.

3) Removed the Eclipse folder entirely. Untarred Eclipse 3.0. Installed MyEclipse 3.8.2. Opened new workspace. Debug perspective crashes with same exception.

This is definitely a MyEclipseIDE installation issue. I’m using OS 10.3 with all of the Java and security patches and completely fresh installations of Eclipse. As I mentioned before, I tried both Eclipse 3.0 and 3.01 with MyEclipseIDE 3.8.1 and 3.8.2. As long as MyEclipse is installed the debug perspective will not work.
Thanks

[Scott Anderson]

Saxon,

OK, I have some questions. How did you install MyEclipse? Using the Mac-specific double-click installer or the manual installer?

Can you clean out the log, restart Eclipse and post the entire log here? Also, can you please post the full configuration available at Help > About Eclipse Platform > Configuration Details?
