Dynamical reverse mapping

Question

Hi,
I didn't manage to do the reverse mapping at runtime.
I have 2 components.
The context of them are described below:
There is only one node in component 1 called "idioms"
In the component 2 (that is the component used called POPUP) there is the node called "columns"
I want to map idioms to columns at runtime. It is a reverse mapping.
I have the code below:
data: lo_node_info type ref to if_wd_context_node_info,
        lo_dyn_node_info type ref to if_wd_context_node_info,
        stru_mapping_info type wdr_context_mapping_info,
        tab_mapping_path type wdr_ctx_element_path_segments,
        wa_path type wdr_ctx_element_name.
  wa_path = 'COMPONENTCONTROLLER.COLUMNS'.
  insert wa_path into table tab_mapping_path.
  stru_mapping_info-component_usage = 'POPUP'.
  stru_mapping_info-controller = 'COMPONENTCONTROLLER'.
  stru_mapping_info-path = tab_mapping_path.
lo_node_info = wd_context->get_node_info( ).
* Map the context node dynamically
  call method lo_node_info->add_new_mapped_child_node
    exporting
      child_name   = 'IDIOMS'
      mapping_info = stru_mapping_info
    receiving
      child_node_info = lo_dyn_node_info.
The mapping hasn't been done. Why?
Thanks a lot.

Hi David,
Thanks for your helping.
I have done what you said, but I am receinving the error below;
Adapter error in &VIEW_ELEMENT_TYPE& "TABS" of view "YSWD_HR_TABLE_POPUP.MAIN": Context binding of property DATA_SOURCE cannot be resolved: Subnode MAIN.IDIOMA_POPUP does not exist
I am passing the node IDIOMA_POPUP as a parameter of the set_data( ) method of the used component.
TABS is the table that I want to populate.
