Hi Dharmakasi,
I change it as you said, and then do debugging, set breakpoint in method ON_NEW_FOCUS, the first time, focus_bo can get BTAdminH, but the second time, get BTDateSet. The same issue happens.
I see another example as below, the superclass is different from my superclass 'CL_BSP_WD_CONTEXT_NODE', do you know how to create one context node with this superclass 'CL_CRM_UIU_BT_DATE_CN'.
Kind Regards
Andie
