In MVC, do i need a View or Page with flow logic for POPUP window

Question

Hi All,
I have the below scenario using the MVC pattern.
I have a main view with 3 trays, each tray has two buttons, for example first tray has Create Order button. When I click on this button, I need a popup window to come with a tableview and a button(Create), where I select some rows and click on the button Create  to create order.
But as per the MVC pattern I canu2019t call the view (popup) from another view(main view).  So should I create a VIEW or PAGE WITH FLOW LOGIC for the popup? .
I need 6 popup to be called from the main view and once the function is done close the popup.
Please suggest me the flow for this scenario.
Cheers,
Srini.

Srini,
1. You can call the view in pop-up because you will be calling the controller using open.window.
Here is the sample code:
method DO_REQUEST .
  data:
        li_vw           type ref to   if_bsp_page,
        lv_form_field   type          string,
        li_md           type ref to   zcl_model01.
  dispatch_input( ).
  li_md ?= get_model( 'm01' ).
  lv_form_field = request->get_form_field( 'invoice_create' ).
  if lv_form_field is initial.
*------ Request to display main page
    li_vw = create_view( view_name = 'main.htm' ).
    li_vw->set_attribute( name = 'model' value = li_md ).
    call_view( li_vw ).
  elseif lv_form_field eq 'true'.
*------ Request to display Invoice page in pop-up
    li_vw = create_view( view_name = 'invoice.htm' ).
    li_vw->set_attribute( name = 'model' value = li_md ).
    call_view( li_vw ).
  endif.
endmethod.
Layout:
      function do_Invoice()
      { var s=0; r=1; w=300; h=300; x=screen.width/2;
        x=x-w/2;
        var y=screen.height/4;
        y=y-h/2;
        popUp=window.open('main.do?invoice_create=true','win','width='+ w
        +',height='+ h +', left=' + x +',top='+ y +');
Option2:
Ofcourse you can't bind the model in page becos those are 2 different things. But all you need to do is access the model to get some value. To know how to access the model from Page w/flow logic look at [this link|Passing model reference to a page in a Popup].
