ASSERTION_FAILED when filling dropdownbykey with sql queries

Question

Hi everybody,
I'm new to WDA, and I am coding a new interface for transaction CBIH82 in EHS.
I am filling a dropdownbykey with a sql query, for the work area.
On the view, the dropdownbykey is populated, but when I click on a button, or when I launch an action, I have the error "ASSERTION_FAILED".
However, if I fill the dropdownbykey manually in the code, I got no error.
Error in IE :
The ASSERT condition was violated

The error is at line 27956.                                                     
And here is my code to fill the dropdownbykey in my wddoinit of my view :
data:
    lieux_de_travail                    type string,
    description_lieux_travail           type string,
    table_record_number_travail         type TABLE OF string,
    table_lieux_travail_full            type TABLE OF string,
    lieux_travail_full                  type string,
    record_number_travail               type string,
    valeur_int                          type i VALUE 0,
    valeur_string                       type string.
SELECT RECNROOT FROM CCIHT_WAH INTO TABLE table_record_number_travail.
LOOP AT table_record_number_travail INTO record_number_travail.
  SELECT WANAM FROM CCIHT_WALD INTO description_lieux_travail WHERE RECNROOT = record_number_travail.
  ENDSELECT.
  SELECT WAID FROM CCIHT_WAH INTO lieux_de_travail WHERE RECNROOT = record_number_travail.
  ENDSELECT.
  IF NOT lieux_de_travail = 'ALOUETTE'.
    CONCATENATE lieux_de_travail description_lieux_travail INTO lieux_travail_full SEPARATED BY ' - '.
  ELSE.
    lieux_travail_full = lieux_de_travail.
  ENDIF.
INSERT lieux_travail_full INTO TABLE table_lieux_travail_full.
ENDLOOP.
data:     NODE_INFO type ref to IF_WD_CONTEXT_NODE_INFO,
          NODE_INFO_ACLOC type ref to IF_WD_CONTEXT_NODE_INFO.
NODE_INFO = WD_CONTEXT->GET_NODE_INFO( ).
NODE_INFO_ACLOC = NODE_INFO->GET_CHILD_NODE( 'INFO_ACLOC' ).
data:    LT_VALUESET type WDR_CONTEXT_ATTR_VALUE_LIST,
         L_VALUE type WDR_CONTEXT_ATTR_VALUE.
valeur_int = 0.
LOOP AT table_lieux_travail_full INTO L_VALUE-TEXT.
  ADD 1 TO valeur_int.
  MOVE valeur_int to valeur_string.
  L_VALUE-VALUE = valeur_string.
  INSERT L_VALUE into table LT_VALUESET.
ENDLOOP.
CLEAR valeur_int.
NODE_INFO_ACLOC->SET_ATTRIBUTE_VALUE_SET(
     NAME = 'LIEUX'
     VALUE_SET = LT_VALUESET ).
The values are stored in the context node "INFO_ACLOC", and cardinality 1.1/0.1, in LIEUX of type String.
Anybody had this error before?
Thank you!

Answer 1

Hi Thomas,
thank you, that was it.
I had a conversion of int to string, and the resulting string was not good.
It looked like as a number in the debug mode, but not in the hexadecimal value.
I did not saw it, because I'm beginning to learn abap too.
