Status: Unverified
FACT(s) (Environment):
OpenEdge 10.x
SYMPTOM(s):
COMBO-BOX doesn't return the correct value for SCREEN-VALUE
COMBO-BOX doesn't return the correct value for INPUT-VALUE
The problem occurs when one of the following action is performed:
Initializing the SCREEN-VALUE before widget is realized
Typing in the value for the COMBO-BOX
Using LIST-ITEM-PAIRS COMBO-BOX.
You get the correct value for SCREEN-VALUE and INPUT-VALUE when clicking on a list item.
CAUSE:
This is a known issue being investigated by Development
FIX:
Use the combo as LIST-ITEM and keep the parity list in a separate Temp-Table with two fields. Referring to this TT still give you the chance to simulate the LIST-ITEM-PAIRS combo-box behavior. This is the relevant code:
/* Defining the Temp-Table and populating it*/
DEFINE VARIABLE myListItemPairs AS CHARACTER NO-UNDO.
DEFINE VARIABLE i AS INTEGER NO-UNDO.
myListItemPairs = "France, FR,Suisse, CH,Etats unis, EU,Grande Bretagne, GB,Canada, CA,Bahames, BA".
DEFINE TEMP-TABLE ttNations
FIELD cName AS CHAR
FIELD cID AS CHAR.
DO i = 1 TO (NUM-ENTRIES (myListItemPairs)) / 2 :
CREATE ttNations.
ASSIGN
cName = ENTRY ( 2 * i - 1 , myListItemPairs )
cID = ENTRY ( 2 * i, myListItemPairs ).
END.
/* Using the Temp-Table to simulate a LIST-ITEM-PAIRS combo-box behavior. */
FIND FIRST ttNations WHERE cName = COMBO-BOX:INPUT-VALUE NO-LOCK NO-ERROR.
IF AVAIL(ttNations) THEN
DISPLAY ttNations.cID.
