Solution ID: P3542
FACT(s) (Environment):
Progress 8.x
Progress 9.x
SYMPTOM(s):
Combo-box is not keeping the default unknown-value within integer or decimal fields
CAUSE:
Expected behaviour.
If your Combo-Box field is defined in Data Dictionary as Initial Value "?" (unknown-value) and the field is integer.
If you assign his screen-value "?" this will save the record with a value of 0 (zero) within the record.
&Scoped-define ENABLED-FIELDS Customer.Customerid Customer.HotelID Customer.CountryID
&Scoped-define DISPLAYED-FIELDS Customer.Customerid Customer.HotelID Customer.CountryID
DEFINE FRAME a
customer.Customerid VIEW-AS FILL-IN
customer.HotelID VIEW-AS COMBO-BOX LIST-ITEM-PAIRS "Hotel 0",0,"Hotel 1",1,"Hotel 2",2
customer.CountryID VIEW-AS FILL-IN
.
ON 'go':U OF FRAME a
DO:
MESSAGE "Screen-Values" SKIP
Customer.CustomerID:SCREEN-VALUE IN FRAME a
Customer.HotelID:SCREEN-VALUE IN FRAME a
Customer.CountryID:SCREEN-VALUE IN FRAME a
VIEW-AS ALERT-BOX.
ASSIGN FRAME a {&enabled-fields}.
FIND CURRENT Customer NO-LOCK.
MESSAGE "Values stored to DB" SKIP
Customer.CustomerID
Customer.HotelID
Customer.CountryID VIEW-AS ALERT-BOX.
DISPLAY {&displayed-fields} WITH FRAME a.
RETURN.
END.
CREATE Customer.
DISPLAY {&displayed-fields} WITH FRAME a.
ENABLE {&ENABLED-fields} WITH FRAME a.
VIEW FRAME a.
WAIT-FOR "go" OF FRAME a.
HIDE FRAME a.
FIX:
You will not be able to do a assign as the example is showing.
You need to check the Screen-Value of the combo-box and do an assign of the unknown-value.
In previous example the assign is done as follow:
ASSIGN FRAME a {&enabled-fields}.
do the following:
ASSIGN Customer.Customerid Customer.CountryID.
IF HOTELID:SCREEN-VALUE IN FRAME a = "?" THEN
ASSIGN HOTELID = "?".
This will save the integer field as Unknown-value instead of 0 (zero).
