Error in dynamic node creation ..........

[Aisurya]

Hi experts,

I am creating a node dynamically in WDDOINT and creating an input field in WDDOMODIFYVIEW , but am getting an error "attribute not found". Am pasting below my code...

Code in WDDOINT of a view :

data lr_par_node       type ref to IF_WD_CONTEXT_NODE_INFO.
    data lr_node       type ref to IF_WD_CONTEXT_NODE_info.
     data lr_node_info1       type ref to IF_WD_CONTEXT_NODE_INFO.
    data lr_node1       type ref to IF_WD_CONTEXT_NODE.
    data lr_attribute  type        WDR_CONTEXT_ATTRIBUTE_INFO.
    data lt_child_node_map                  type wdr_context_child_info_map.


*****to get context parent node information
    lr_par_node = wd_context->get_node_info( ).
*****to get child node of the parent
    lt_child_node_map = lr_par_node->get_child_nodes( ).
*****check for the existence of node
    read table lt_child_node_map transporting no fields with table key name = `RESULT`.

    if sy-subrc = 0.
      " REMOVE_CHILD_NODE
      lr_par_node->remove_child_node( `RESULT` ).
    endif.

  endif.
endmethod.

Pls help me in this.....

Thanks

Issue is resolved by own.

Hi,

looking at code it seems that you are adding textview and inputfield. please check in debugging if the correct context node/attribute is being created and you are providing its reference while adding UI elements.

Thanks,

Chandra
