Using view context attribute values in view methods

Question

Hello,
I have a view context mapped to a window context.  The window context has a supply function that gets some data.  I would like to use some of this data in one of my view methods but can't seem to find the syntax to use the values in the mapped view context attributes.  I know for displaying on the view you map the screen field to the context attribute but I just need to use this value in a method.  Any help will be greatly appreciated.
Thank you,
JR

Hi Joseph,
If you already had mapped the view context with the window context, all you have to do in the view method is to read the view context. For this, you can use the next code:
  DATA: lo_node      TYPE REF TO if_wd_context_node,
        lo_element   TYPE REF TO if_wd_context_element,
        lv_attribute TYPE wd_this->element_node-attribute.
  lo_node = wd_context->get_child_node( name = wd_this->wdctx_node ).
  lo_element = lo_node->get_element( ).
  lo_element->get_attribute(
    EXPORTING
      name =  `ATTRIBUTE`
    IMPORTING
      value = lv_attribute ).
This is supossing you have a node named 'NODE' with an attribute named 'ATTRIBUTE'.
Also, you can use the Web Dynpro Statement Structure. It's a wizard that helps you to generate some code. The icon is like a magic wand.
