How to get attribute value of a node

Question

Hi experts
I have a mapped node in my view context from component controller context. This node consists of 2 value attributes inside
Example:
NODE1             -
> Cardinality 1..1, seleciton 1..1
   -- x_date         -
> type DATS
   -- x_years        -
> dec3
How do I get the attribute value attr1 and attr2 ??
Here is my code in my view method
  DATA: lr_node_info TYPE REF TO if_wd_context_node_info,
        l_date       TYPE dats,
        l_xyears     TYPE i.
  lr_node_info = wd_context->get_node_info( ).
  lr_node_info = lr_node_info->get_child_node('NODE1').
   l_date       = lr_node_info->get_attribute( name = 'X_DATE' ).
   l_xyears     = lr_node_info->get_attribute( name = 'X_YEARS' ).
It does not seems to work since it says < the result type of the function method can not be converted into the result type L_DATE>
I try to understand why but not sucessful, please help and thank you for your kindness

Hi Dean,
Regading uour problem of reading the attributes value of the context node, you have to  use the code wizard. that ia avaliable on the top toolbar when you are inside the View Method
There is option to read context  select that radio button option and then thru F4 help
if you can select the node then Code is automatically generated with variable declaration.!!
Like this :
  DATA lo_nd_node1 TYPE REF TO if_wd_context_node.
    DATA lo_el_node1 TYPE REF TO if_wd_context_element.
    DATA ls_node1 TYPE wd_this->element_node1.
    DATA lv_x_date LIKE ls_node1-x_date.
    DATA lv_x_year LIKE ls_node1-x_year.   
  navigate from <CONTEXT> to <NODE1> via lead selection
    lo_nd_node1 = wd_context->get_child_node( name = wd_this->wdctx_node1 ).
  get element via lead selection
    lo_el_node1 = lo_nd_node1->get_element(  ).
  get all declared attributes
    lo_el_node1->get_static_attributes(
      IMPORTING
        static_attributes = ls_node1 ).
    lv_x_date = ls_node1-x_date.
    lv_x_date = ls_noe1-x_year.
if you can select the attribute then Code is automatically generated with variable declaration.!!
DATA lo_nd_node1 TYPE REF TO if_wd_context_node.
  DATA lo_el_node1 TYPE REF TO if_wd_context_element.
  DATA ls_node1 TYPE wd_this->element_node1.
  DATA lv_x_date LIKE ls_node1-x_date.
navigate from <CONTEXT> to <NODE1> via lead selection
  lo_nd_node1 = wd_context->get_child_node( name = wd_this->wdctx_node1 ).
get element via lead selection
  lo_el_node1 = lo_nd_node1->get_element(  ).
get single attribute
  lo_el_node1->get_attribute(
    EXPORTING
      name =  `X_DATE`
    IMPORTING
      value = lv_x_date ).
Hopes this will helps you.
