Iterator Error

Question

Hi Experts,
Now Im working with Table Iterator. For that Im following Web blog wrote by Brain,
/people/brian.mckellar/blog/2003/10/31/bsp-programming-htmlb-tableview-iterator
In the Web log, I have the doubt when creating Drop down list Box.
I wrote the following code from the blog,
WHEN 'CURRENCY'.
       IF p_edit_mode IS NOT INITIAL.
        p_replacement_bee = CL_HTMLB_DROPDOWNLISTBOX=>FACTORY(
                           id                = p_cell_id
                           selection         = m_row_ref->CURRENCY
                           table             = me->m_currencies_ref
                            nameOfKeyColumn   = 'NAME'
                            nameOfValueColumn = 'VALUE' ).
       ENDIF.
But it shows the following Error,
<b>Class ZCL_BCM_SDN_ITERATO1,Method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START     41     @0A\QError@
Field "M_CURRENCIES_REF" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement . . . . . . . . . .     </b>
Please any one help on this issue. I couldn't rectify this Error,
Thanks in Advance,

Answer 1

As per the blog, it should be as follows:
In the iterator class create the attribute:
M_CURRENCIES_REF type ref to DATA
<b>To Fill the M_CURRENCIES_REF:</b>
IF_HTMLB_TABLEVIEW_ITERATOR~GET_COLUMN_DEFINITIONS.
  FIELD-SYMBOLS: <currency> TYPE IHTTPNVP.
  CLEAR me->m_currencies.
  APPEND INITIAL LINE TO me->m_currencies ASSIGNING <currency>.
  <currency>-NAME = 'USD'. <currency>-value = 'US Dollar'.
  APPEND INITIAL LINE TO me->m_currencies ASSIGNING <currency>.
  <currency>-NAME = 'EUR'. <currency>-value = 'Euro'.
  APPEND INITIAL LINE TO me->m_currencies ASSIGNING <currency>.
  <currency>-NAME = 'ZAR'. <currency>-value = 'SA Rand'.
  GET REFERENCE OF me->m_currencies INTO me->m_currencies_ref.
Hope this will solve your problem.
