hi

avoid any of these :

1 in a component which already One view say VIEW , u r creating the other view with same name

2 for ur view in component with the name layout u try to add the component usage with the

same name, what are the names of your views in the application .

The POPUP is not an ALV.

DATA lo_el_task TYPE REF TO if_wd_context_element.

DATA ls_task TYPE wd_this->element_task.

• navigate from <CONTEXT> to <TASK> via lead selection

lo_nd_task = wd_context->get_child_node( name = wd_this->wdctx_task ).

• get element via lead selection

lo_el_task = lo_nd_task->get_element( ).

CALL METHOD lo_nd_task->get_static_attributes

EXPORTING

index = r_param->index

IMPORTING

static_attributes = ls_task.

DATA lo_nd_task_disp_info TYPE REF TO if_wd_context_node.

DATA lo_el_task_disp_info TYPE REF TO if_wd_context_element.

DATA ls_task_disp_info TYPE wd_this->element_task_disp_info.

• navigate from <CONTEXT> to <TASK_DISP_INFO> via lead selection

lo_nd_task_disp_info = wd_context->get_child_node( name = wd_this->wdctx_task_disp_info ).

• get element via lead selection

lo_el_task_disp_info = lo_nd_task_disp_info->get_element( ).

CLEAR ls_task_disp_info.

MOVE-CORRESPONDING ls_task TO ls_task_disp_info.

One last question, view that you are trying to display is in the same component...

If yes, is it in the same window where the ALV views are also there..

If yes, then this will go for a dump..as stated..

Do one thing..Create one more window inside this embed the view that you want to show it in popup...

Ans show this popup as Modal window by passing the window name..

Is this clear.

Hi Lekha,

I am using two windows . One for ALV and other for POPUP.

cheers,

Try to uncomment this

• close_in_any_case = abap_true

and test it out..

some where the refernce of the window is already embeded.

[Former Member]

Thanks Lekha for your continious support.

I've uncommented and tested it.

But still same problem.

Do one thing,

When first time the popup is created then store the referces to the gloabl variables of view attributes..

Form second time on wards try to use these references..instaed on exectuing the same code again for popup creation..

Try it out..

Hi Sravan,

Firstly check for any existing popup and if exist close that popup.

DATA lo_api         TYPE REF TO if_wd_view_controller.
DATA lo_window_ctlr TYPE REF TO if_wd_window_controller.
DATA lo_popup       TYPE REF TO if_wd_window.

lo_api         = wd_this->wd_get_api( ).
lo_window_ctlr = lo_api->get_embedding_window_ctlr( ).
lo_popup       = lo_window_ctlr->get_window( ).

IF lo_popup IS BOUND.
  lo_popup->close( ).
ENDIF.

Write that code before creating popup.

Hope this will resolve the defect.
