Cannot access Created Context Attribute from Component Controller

[Former Member]

Hello All,

I have added a new attribute to a node in my component controller 'LOGONUID' and I cannot access it within my windows within the WDA application.

DATA lo_nd_url_param TYPE REF TO if_wd_context_node.
  DATA ls_workset TYPE wd_this->element_workset.
  "DATA ls_logonuid TYPE wd_this->element_logonuid.

 

I get an error as soon as I try to activate this code in my method in my W_MAIN

In my component controller I do not see it reference in the SAP generated code in my WD_THIS IF_COMPONENTCONTROLLER?

* Intf.: ig_componentcontroller

    end of Element_cuifcontext,
    Elements_cuifcontext type
       standard table of Element_cuifcontext
       with default key.

I want it to be declared as the constant 'WORKSET'

thank you

This declaration is not right. There is no element logonuid, you have the attribute inside a node. workset is a node and thats why you can declare that way.

easiest way is to declate

data lv_logonuid type <ddic type> or

data lv_logonuid type wd_this-><node name>-logonuid.

You can also use the code generator in (CTRL +F7 ) to get/set attributes.

you're right Baskaran, I did have that wrong.

The problem I am running into now is accessing the attribute of the context.

  CLEAR wa_parameter.
  READ TABLE it_parameter WITH KEY name = 'LOGONUID' INTO wa_parameter.
  IF sy-subrc EQ 0.
    ls_workset-logonuid = wa_parameter-value.
  ENDIF.

*--Save LOGONUID parameter to context
  lo_nd_url_param = wd_context->get_child_node(  name = wd_this->wdctx_logonuid  ).
  lo_nd_url_param->set_static_attributes(
     static_attributes = ls_workset ).	

My Problem is that, it does not think that wdctx_logonuid exists although I have added as a attribute to my node?

See post above that SAP generated code does not show it as a constant?

hi everyone,

I got mixed up... I was thinking that I was referencing the ATTRIBUTE and not the entire NODE.

This code here corrected my issue:

  " Get parameter values
  CLEAR wa_parameter.
  READ TABLE it_parameter WITH KEY name = 'WORKSETID' INTO wa_parameter.
  IF sy-subrc EQ 0.
    ls_workset-worksetid = wa_parameter-value.
  ENDIF.

*---------------------- END OF  todo ------------------------
  " Get parameter values
  CLEAR wa_parameter.
  READ TABLE it_parameter WITH KEY name = 'LOGONUID' INTO wa_parameter.
  IF sy-subrc EQ 0.
    ls_workset-logonuid = wa_parameter-value.
  ENDIF.
*---------------------- END OF  todo ------------------------

*--Save URL parameter to context
  lo_nd_url_param = wd_context->get_child_node(  name = wd_this->wdctx_workset  ).
  lo_nd_url_param->set_static_attributes(
     static_attributes = ls_workset ).
