Hi,

 FPM application is not running

Please give glucose to it. It may help to run

Coming to the error, This error occurs when the object is not instantiated.  Please check in ST22 transaction, at which point you are getting the short dump.

Hi Deepa,

I tried the steps in the link provided by you and it is working fine for me. As there is no custom code in the scenario, This error is mainly due to incorrect configuration creation. Please check your configuration.

Also, Are you executing the Web Dynpro application directly?  As mentioned in the link, Expand the application and Test the application Configuration.

If you want to run the Web Dynpro application directly. Double click on the Web dynpro application and go to Parameters tab and Enter the parameter WDCONFIGURATIONID with value your Configuration name and save. Now test your application.

Also in page 3 of the provided link, You need to click on 'Go to Component Configuration' button for both the Component usage and IDR_USAGE.

Hope this helps u.,

Revert back incase of further clarifications.

Thanks & Regards,

Hello,

Can you paste the snapshot of st22 here.

Getting Null object error is very common id Webdynpro. Sometimes we use code wizard and delete few things and while deleting we delete important object reference statements.Please re-generate the code using code wizard it will be corrected.If not check in debugging which node is not getting reference and see object reference is available in code or not.

Hope it will fix.
