Mapping context subnodes of WD ABAP with context of Interactive Form

Question

Hi everyone,
I'm facing a problem here passing my WD subnodes to the context of the interactive form.
I managed to pass a node with only attributes but not with subnodes in it.
The code I used is really basic, here is a sample :
  DATA t_affectation TYPE wd_this->elements_t_affectation.
  DATA t_el_affectation TYPE wdr_context_element_set.
  DATA nd_dropdown_project TYPE REF TO if_wd_context_node.
  DATA nd_dropdown_customer TYPE REF TO if_wd_context_node.
  DATA lt_dropdown_customer TYPE wd_this->elements_t_dropdown_customer.
  DATA lt_dropdown_project TYPE wd_this->elements_t_dropdown_project.
  LOOP AT t_el_affectation INTO el_affectation.
    nd_dropdown_project = el_affectation->get_child_node( name = wd_this->wdctx_t_dropdown_project ).
    nd_dropdown_customer = el_affectation->get_child_node( name = wd_this->wdctx_t_dropdown_customer ).
    nd_dropdown_project->bind_table( new_items = lt_dropdown_project ).
    nd_dropdown_customer->bind_table( new_items = lt_dropdown_customer ).
  ENDLOOP.
But i get a dump telling me
Termination occurred in the ABAP program "CL_WD_ADOBE_SERVICES==========CP" -
  in "NODE_2_DDIC".
The main program was "SAPMHTTP ".
In the source code you have the termination point in line 32
of the (Include) program "CL_WD_ADOBE_SERVICES==========CM00L".
and the dump occurs as soon as it explores the subnode:
   20 * depending on the cardinality, it either represents a structure or i
   21   if lr_node_info->is_multiple( ) = abap_false.
   22 *   it represents a structure
   23     lr_element = i_node->get_element( index = 1 ).
   24     node_elem_2_struct(
   25       i_element   = lr_element
   26       i_parent    = i_parent
   27       i_node      = i_node
   28       i_node_info = lr_node_info ).
   29   else.
   30 *   it represents a table
   31     lt_elements = i_node->get_elements( ).
------>     assign i_parent->* to <itab>.
   33     loop at lt_elements into lr_element.
   34 *     create a new line inside of the itab
   35       insert initial line into table <itab> reference into lr_data.
Does any of you has an idea ? I would be most grateful.
Thank you
Regards,
Alexandre

It's ugly, but it's true:
At this point in time, Web Dynpro for ABAP has only one Interactive-Forms-specific standard event (compared to the 2 in Java), which is the Submit event. I am hoping that both Web Dynpro worlds will be on the same level in terms of features in the next release.
