Where the table's rows are gone???

Hello

I created a popup by using the below code; I placed a Table UI element with 4 fields/column, among that 2 are with input enabled and 2 are ReadOnly type

wd_this->w_window = lo_window_manager->create_window(

When i am coming from MAIN / HOME view, am seeing below with required rows (here all code of WDDOINIT method is triggering)

When i am coming from HANDLE_FROM_WINDOW view, am seeing below with NO rows (here only some piece of WDDOINIT method is triggering)

Pls. let me know Why the rows are disappearing????

Thank you
