Error while removing configuration from NWDS.

[Former Member]

Hi,

I am trying to remove the configuration from Development Configuration perspective in NWDS. I got a Null pointerException, stating that "istNodesWhereSomethingIsCheckedOut".

However no file is checked out in my workspace.

Can you please help me regarding this problem?

Following is the error message.

Hi,

Please make sure there are no open activities or activities waiting for release before removing the configurations

Change Workspace settings from the default one to a new location:

http://help.sap.com/saphelp_nw70/helpdata/EN/03/eb813f0e614a18e10000000a114084/frameset.htm

Nex time you open NWDS, it will have clean workspace, so you can connect to NWDI and bring in any project from DTR.

Thanks

This problem is solved...

Check for open activities in Development configuration perspective: If no activities found then delete the workspace. Then try to import the new configuration in new workspace.

It is working fine in my case.
