Tree context node error.

Hello Experts,

Here i am having a tree view (standard UI component which is enhanced). There is one parent node, its class name is  "ZL_XXX_CN01" and a child node, class name "CL_XXX_CN02".

Here i have to add my code in the get_ method of the child node. But when i am redefining the get_ method system is asking for the access key.

Can any one help me here please.

Thank you

Sai
