how to open a popup and get some data from a model class

[Former Member]

Hi experts,

mi problem is the next.

I am opening a popup from a view that is controlled by a controller named identificador.do, the controller class is z_identity_cl.

the window that is opened is other view controlled by nocupentes.do, with a controller class, z_nocupantes_cl.

In the do_init event of the z_nocupantes class i have added the next code:

<i> DATA: cl_parent TYPE REF TO Z_IDENTtity_CL.

• Recuperamos el atributo parent

cl_parent ?= me->m_parent.

• model is the class i want to recover, it is defined in the attibutes of the class z_identity_cl

model ?= cl_parent->get_model( 'mo' ).</i>

When i open the popup i get the next error:

<i>BSP exception : the object numero_ocup.htm(this is the page i want to open) in URL sap/ZHR_PDWEB_GDPT/numero_ocup.htm is a view. Initialize the controller.</i>

what do i have to do?

any help?

thanks in advance

Hi Eduardo,

you should be calling the Controller in the URL not the View. after calling the controlles in the URL create the view in the DO_REQUEST of the Controller. This should resolve the issue.

In the the DO_INIT define the Parent class of the Controller.

METHOD do_init.
  DATA: lr_my_parent TYPE REF TO zcl_hr_main_control.


* set (MVC) model
  lr_my_parent ?= me->m_parent.
  set_model( model_instance = lr_my_parent->model

                   model_id = 'Z' ).
  me->model = lr_my_parent->model.
ENDMETHOD.



method DO_REQUEST.

* datadeclaration
  DATA: abs      TYPE REF TO if_bsp_page.

* if input is available, dispatch this input to subcomponent.
* this call is only necessary for toplevel controllers.
  dispatch_input( ).

* if any of the controllers has requested a navigation,
* do not try to display, but leave current processing
  IF is_navigation_requested( ) IS NOT INITIAL.
    RETURN.
  ENDIF.

* output current view (create, set attibutes, and call)
  abs = create_view( view_name = 'to_disp.htm' ).

* set attribute model if needed
  abs->set_attribute( name = 'model' value = model ).

* call master views
  call_view( abs ). "calls itself

endmethod.

Hi Amandeep ,

You were right with the call to the controller, i was calling the page instead of the controller.

Now, my problem is the next:

when in the class controller of the view, in the DO_INIT, I make the assignation:

• set (MVC) model

lr_my_parent ?= me->m_parent.

me->m_parent hasn't got anything, the reference is null, why can this happen?

Thanks alot!!!

Hi,

first of all you need a controller for your view,

and register him to your main application

have a look at <a href="/people/koen.labie2/blog/2006/11/17/showhelp-functionality-with-pop-up--part2 weblog</a>,

maybe it will help, I pass model to popup

grtz,

Koen
