Hi all,

I need to call a dialog box from a method in the component controller. It would be helpful if u could post the code too.

Thanks,

Maksim,

No, it is not the same view from which i call the comp controller. Sorry, I guess I was not clear with my question. This is how it is:

I'm calling a method in the component controller from a method in view, say 'BOOKVIEW' which is in 'MAINWINDOW'.

wd_comp_controller->add_to_cart( ).

In the ADD_TO_CART method of the component controller, i need to open a dialog window. The dialog window's name is 'OPTIONWD' and there's a view embedded in it called 'OPTIONVIEW'. and i need to write the code to open this popup window in the 'ADD_TO_CART' method.

Thanks for all your help.

Sorry, Spravanthis, seems like I don`t have an idea how to solve "An Instance of the View OPTIONWD Already Exists in the Component" issue. May be <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/9e242bf5-0901-0010-c99c-83c180163c73">this tutorial</a> can be useful for you.

Or in your system you will find the detailed example component WDR_TEST_POPUPS_RT_00. It is located in package SWDP_TEST.

Hi Sravanthi,

The exception is raised whenever a view becomes visible twice. It seems that view OPTIONVIEW was about to be displayed twice. This is not possible.

Btw.: Please use the button enumerations that are offered for popup windows. I saw that your call does not specify them.

Best regards,

I have a method in a view of the main window that calls a method in the component controller. the code goes like this:

wd_comp_controller->add_to_cart( ).

In the method add_to_cart of the component controller, i need to call a popup window. I created a window and embedded a view in that window. and i wrote the code that i previously sent to call this dialog box.

So, OPTIONWD window contains view which should be in popup? Is it not the same view from where you call component controller?

Hi Maksim,

this is the code i wrote:

DATA: api_component TYPE REF TO if_wd_component,

window_manager TYPE REF TO if_wd_window_manager.

api_component = wd_this->wd_get_api( ).

window_manager = api_component->get_window_manager( ).

wd_this->window = window_manager->create_window(

window_name = 'OPTIONWD'

close_button = abap_false ).

wd_this->window->open( ).

When i test it, this is the error i get.

"An Instance of the View OPTIONWD Already Exists in the Component"

how do i correct it?

Thanks,

Sravanthi

Hi Sravanthi,

Hm, what WD component strucutre you have? What is window-views hierarchy? From which controller are you calling menyioned code?

Best regards, Maksim Rashchynski.

Hi Sravanthi,

data:
    l_componentcontroller_api type ref to if_wd_component.
    l_componentcontroller_api = wd_this->wd_get_api( ).

And afterwards use

IF_WD_COMPONENT->GET_WINDOW_MANAGER->CREATE_WINDOW
