Configuration Problem in webdynpro using Custom containers

Hi,

I am practicing the web dynpro examples for beginners using the below Link

Web Dynpro for ABAP: Tutorials for Beginners [original link is broken]

Its configuration example number 5.

I did as explained in the example but I am unable to get the required output.

I found only one difference where the CONFIGURATION STATE is POSSIBLE in my application and in the tutorial is AVAILABLE.

Could anyone please help me in this issue
