Purpose: Accessing Component Controller or Custom Controller in a context node class
The COMP_CONTROLLER is a protected variable. Using reference to Window Controller will access the component controller.
1) In the View Controller’s Implementation class (ZL_XXXXX_IMPL) create a public instance method Get_Window ( ).
method GET_WINDOW.
rr_window = me->view_manager->get_window_controller( ).
endmethod.
2) In the Context Node Class (CNXX), create a public instance variable gv_owner of type view controller’s implementation class (ZL_XXXXX_IMPL).
3) In the Context Node Class (CNXX) redefine the method IF_BSP_MODEL~INIT if needed with this code.
method IF_BSP_MODEL~INIT.
gv_owner ?= owner.
endmethod.
4) Accessing the component controller in the method ON_NEW_FOCUS of the Context Node Class (CNXX)
method ON_NEW_FOCUS.
DATA:lr_window TYPE REF TO cl_XXXXX_window_impl, " Window Impl Class
lr_comp TYPE REF TO zl_XXXXX_bspwdcomponen_impl, " Component Controller Impl class
lr_access TYPE REF TO if_bol_bo_property_access,
lr_vc TYPE REF TO zl_XXXXX_impl. " View Controller Impl class
lr_vc ?= gv_owner.
lr_window ?= lv_vc->get_window( ).
lr_comp ?= lr_window->m_parent.
lr_access ?= lr_comp->ztyped_context->gvproduct->collection_wrapper->get_current( ).
endmethod.
