Error message display in web dynpro application?

Question

Hi All,
In my web dynpro application I am displaying error messages but the focus does not go to the field where error occured and also if I click on the error message it does not lead to the place of error.
And also when I navigate to another view the error message does not go.
Below is my code:
*    report message
      DATA err1_text TYPE syst-msgv1.
      err1_text = wd_assist->if_wd_component_assistance~get_text( key = '002' ).
      CALL METHOD lo_message_manager->report_t100_message
        EXPORTING
          msgid      = 'ZAA'
          msgno      = '005'
          msgty      = 'E'
          p1         = err1_text
        RECEIVING
          message_id = lo_text.
Please suggest me the way to do it.
Thanks & Regards

Hi,
I got your point.. in the BIND_TABLE( set_intiail_elemts = abap_true) change this to ABAP_FALSE.
Because of this you are gettng the intiial values. Eventhough your table has no BALNK/space records.
bind a single element
  node->bind_table(
    new_items             =  lt_year_list
    set_initial_elements = abap_true ).
change as
bind a single element
  node->bind_table(
    new_items             =  lt_year_list
    set_initial_elements = abap_false ).
You can use this code - I have tjhe dropdwon for projects event I'm doing the same.
navigate from <CONTEXT> to <PROJECT> via lead selection
  lo_nd_project = wd_context->get_child_node( 'PROJECT' ).
***Gets the selected project id from drop down
  if lo_nd_project is not initial.
    CALL METHOD lo_nd_project->GET_LEAD_SELECTION
      RECEIVING
        ELEMENT = lo_el_project.
get all declared attributes
    if lo_el_project is not initial.
      lo_el_project->get_static_attributes(
        IMPORTING
          static_attributes = ls_project ).
change your code to 
lo_nd_year_list = wd_context->get_child_node( name = wd_this->wdctx_year_list ).
***Gets the selected project id from drop down
  if lo_nd_year_list is not initial.
    CALL METHOD lo_nd_year_list->GET_LEAD_SELECTION
      RECEIVING
        ELEMENT =  lo_el_year_list .
  IF lo_el_year_list IS NOT INITIAL.
    get single attribute
    lo_el_year_list->get_attribute(
      EXPORTING
        name =  `YEAR`
      IMPORTING
        value = lv_year ).
