Unable to create part ...

[former_member188498]

Hello,

I have just recently installed NetWeaver Developer Studio

2.0.9. Everything was going well until today. Whenever I

doubleclick any View, I get the following message :"Unable

to create part: App1View. An error has occurred when

creating this editor. (where App1View is sample view).

I've checked the log file and there was the following

entry

!ENTRY org.eclipse.ui.workbench 4 2 cze 14, 2006 14:28:18.390

!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".

I dont know how to fix this, except maybe by installing everything once again.

If somebody has solution for this, I would apreciate it very much.
