Fill the dynamic context node

Hello gurus,

I have created a context node dynamically using class cl_wd_context_node_info. I added the attribute. But when i try to populate the attribute with sme value, i get an error ' node does not contain any elements'. What is the problem?

I have attached the code with this post in a text file as i don't know how to paste a code snippet in this new version of forum.

Regards,
