Hi,

This is probably something completely stupid that I just cannot see, but my function keys are not working correctly in myeclipse any more. I can hit ctrl-F11 to run the last launched project, but if I hit F11 to debug the last launched application myeclipse shuts down. Also, in debug, I cannot use any of the function keys (f5, f6, etc) to step though/out of/over code. This has only started happening in the last few days so I figure I must have changed some setting, but I can’t seem to find what it is. Anybody got any ideas?

Barry,

While the log entry looks a little disconcerting, I don’t think it’s related to the issue you’re seeing. Were the function keys working properly and then just “went bad”? Did something change (JVM, install new stuff, update, etc) prior to this happening? The issue might be that the Eclipse plugin cache got stale as it sometimes does not cleanly rebuild after updates. To rectify the problem you’ll need to restart Eclipse with the -clean flag one time: eclipse.exe -clean

That might resolve the problem. Other than that, we need to determine what changed and if the issue is isolated to one file, one project, one workspace, or occurs in other workspaces / projects / files.

Scott,

I didn’t think the error had anything to do with it, but it was the only error in there so I figured I would post it.

Yes, the function keys were working, and then ‘went bad’. I’m not sure what changed. I haven’t updated the jvm, or installed any new stuff.

I tried restarting with the -clean flag yesterday with no luck. I just tried again with no luck.

The issue is not isolated to one file, one project, or even one workspace.

Just did a reinstall and everything is back to normal. Not sure what the issue was, but I am just happy that it has been resolved.

thanks,

Barry,

Very odd. Truthfully, I’ve had an install of Eclipse “go bad” as well. And it was my dev instance of Eclipse without MyEclipse installed. I did the same as you to fix it. Big hammer, but it works. 🙂

Glad you’re back up and running.
