Dropdown getting deleted , when called in popup

Question

Hi All,
When i press a button on my main view i call a popup view.
In the popup view i need to add dropdowns on "Add dropdown Button"
When i press the button once the  dropdown is created.
When i press the button for second time the second dropdown doesnt gets created.
In debugging i can just see that the navigation goes to onaction of the add button and then modify view.
and then nothing happens.
Can some one please help me with this?

Answer 1

On Add dropdown
lo_nd_cn_rulehead_edit2->bind_table( new_items = lt_cn_rulehead_edit2 set_initial_elements = abap_true ).
   cl_wd_dropdown_by_idx=>new_dropdown_by_idx(
  EXPORTING
     bind_texts   = 'CN_RULEHEAD_EDIT2.CA_RULEHEAD_EDIT2'
      id          = 'EDIT_DROP2'
       RECEIVING
      control    = lr_input1 ).
when i press the button again (this dropdown doesnt gets created)
   cl_wd_dropdown_by_idx=>new_dropdown_by_idx(
  EXPORTING
     bind_texts  = 'CN_RULEHEAD_EDIT3.CA_RULEHEAD_EDIT3'
      id          = 'EDIT_DROP3'
       RECEIVING
      control    = lr_input2 ).
    lr_matrix = cl_wd_matrix_head_data=>new_matrix_head_data( lr_input2 ).
   lr_input2->set_layout_data( lr_matrix ).
    wd_comp_controller->lr_container->add_child(
        the_child = lr_input2
I think there is some other problem of modify view because when first dropdown is created it works fine
and when second dropdown is created it gives problem
