The Web Dynpro Application 'WebAdminApp' has expired.

Hello all,

I am getting this error when I click on anything from /nwa.

The Web Dynpro Application 'WebAdminApp' has expired. Restart the application using the Refresh button or via the following link WebAdminApp.

I have to configure LogOn Group for the WebDispatcher ( to be able to see the logon group from the java system) and from this link:

Logon Group Configuration - System Landscape Administration with SAP NetWeaver Administrator - SAP Library

I got the solution:

Activities

You can display the overview page of the existing logon groups if you choose System Management  →Configuration  →  Logon Groups. The Logon Groups frame on the right contains a table that lists all logon groups on all registered systems.

:

So, I started /nwa and when I click on Configuration, I am getting:

The Web Dynpro Application 'WebAdminApp' has expired. Restart the application using the Refresh button or via the following link WebAdminApp.

Can you suggest me a solution?

thx

Chris
