context binding issue

[Former Member]

Dear gurus!

Component contains 2 different views and a custom controller.

First view is containing custom f4 help. Here is the V_GETTER for the corresponding node attribute:

method GET_V_TOCH.



  data:

ls_map type IF_BSP_WD_VALUEHELP_F4DESCR=>GTYPE_PARAM_MAPPING,

lt_inmap type IF_BSP_WD_VALUEHELP_F4DESCR=>GTYPE_PARAM_MAPPING_TAB,

lt_outmap type IF_BSP_WD_VALUEHELP_F4DESCR=>GTYPE_PARAM_MAPPING_TAB.



  ls_map-context_attr = 'TOCH'.

  ls_map-f4_attr = 'KEY'.



  append ls_map to: lt_inmap, lt_outmap.



  create object rv_valuehelp_descriptor

    TYPE

      CL_BSP_WD_VALUEHELP_F4DESCR

    EXPORTING

      iv_help_id                  = '(Z_SEARCHTOCH)'

      iv_help_id_kind             = IF_BSP_WD_VALUEHELP_F4DESCR=>HELP_ID_KIND_COMP

      iv_input_mapping            = lt_inmap

      iv_output_mapping           = lt_outmap.



endmethod.

class Z_SEARCHTOCH provides me with the TOCH values. The similar node exists in the Custom controller. The binding is provided in CREATE_ method:

owner->do_context_node_binding(

    iv_controller_type = CL_BSP_WD_CONTROLLER=>CO_TYPE_CUSTOM

    iv_name = 'ZPRINT_COMP/ZMYCONTROLLER'               "#EC NOTEXT

    iv_target_node_name = 'TOCH'

    iv_node_2_bind = TOCH  ).

Also on this view I've got a button with an Action connected to it. With the action handler I want to popup a table view

with rows dependant on user choice in the f4 help.

So, I've created second view type table with corresponding context node. Here in CREATE_ method I'm trying to access custom controller's context to get the user input which should be in the TOCH attribute of the TOCH context node.

lr_cuco ?= owner->get_custom_controller( 'ZPRINT_COMP/ZMYCONTROLLER' ).



    lr_node = lr_cuco->typed_context->toch->collection_wrapper->get_current( ).



 string = lr_node->GET_PROPERTY_AS_STRING( IV_ATTR_NAME = 'TOCH' ).

here lr_cuco is bound, lr_node is bound too, but string contains no desired value!

What am I doing wrong?

popup is carried out like this:

call method comp_controller->window_manager->create_popup exporting

            iv_interface_view_name = 'ZPRINT_COMP/POPUPWINDOW'

                    iv_title = 'print'

                    iv_usage_name = 'ZPRINT_USAGE'

                    receiving

                    rv_result = m_popup_confirm.



                call method m_popup_confirm->set_on_close_event

                exporting iv_view = me iv_event_name = 'POPUP_CLOSED'.

                m_popup_confirm->open( ).

Sincerely, Ivan.

Hi Ivan

You need to explicity bind the context node to the popup window. Just before lr_popup->window

Steps

1. In Run time repository for Compoent Interface for Popup expose the context node that you need to bind.

2. In the code just before lr_popup->open.

Get the reference of the desired context node of popup view using lr_popup->GET_Context_node

Add the entity/collection to this reference.

Yes, it works this way, of course.

Still I'm wondering why I can't access custom controller's context from the popup...

Thank you anyway.
