Context node does not contain any elements

Question

Hi Masters,
                 I create a node dynamically from structure using CL_WD_DEMO_DYN_MODEL->create_nodeinfo_from_struct method. my code as
nd_field_info = nd_field->get_node_info( ).
wd_this->zwd_assist->create_nodeinfo_from_struct( EXPORTING
  parent_info = nd_field_info
  structure_name = dotablename
  is_multiple = abap_true ).
When am set the data to context then it gives the error like node does not contain any elements, but i verified the attributes using nodeinfo then all attributes will be displayed, but when value inserting time it throws error.
Waiting for Your Response...
Advance Thankyou
Regards,
Sathya

Hi sathya ,
the method you using is absolute , the replacement for the methos is  if_wd_context_node_info->add_new_child_node
pls refer the sample code to create a dynamic Node .
DATA: pa0001  TYPE REF TO cl_abap_structdescr,
           comp_tab     TYPE cl_abap_structdescr=>component_table,
           struct_type     TYPE REF TO cl_abap_structdescr,
          ls_pa0001   ?= cl_abap_typedescr=>describe_by_name('P0001').
          comp_tab      = p0001->get_components( ).
          struct_type   = cl_abap_structdescr=>create( comp_tab ).
  struct_type = cl_abap_structdescr=>create( comp_tab ).
* now the nodeinfo is created
  node_info = wd_context->get_node_info( ).
  node_info = node_info->add_new_child_node(
    name                         = 'MY_NODE'
    IS_MANDATORY                 = ABAP_true
    IS_MULTIPLE                  = ABAP_true
    STATIC_ELEMENT_RTTI          = struct_type
    IS_STATIC                    = ABAP_false
refer DEMODYNAMIC component for dynamic creation of node
