Hi!

After working a while myeclipse will show an popup, reporting a NPE has occurred. The popup will be shown on actions in the UI like changing editor tabs until myeclipse is restarted, which “solves” the problem until it appears again.
Environment is MyEclipse Build id: 7.1.1-20090310 on KDE 4.2 on openSUSE 11.1.

Thanks, regards!

Hi,
It seems like your workspace could be corrupt. Have you tried using the -clean command to fix this issue?

Could you also check if the problem persists in a new workspace as well.
