Status: Unverified
FACT(s) (Environment):
Dynamics 2.1A
SYMPTOM(s):
Lookups not blank
Lookup displays value of previous record
A child viewer has no record to display
Dynamics 2.1A02
CAUSE:
Known issue fixed in 2.1A03
If you have a groupassign linked viewer with lookups and you navigate through the parent records of the viewer until you come to a parent record that has no child records, then the lookup can display the value of the previous child record instead of blank.
CAUSE:
Bug# 20031203-032 fixed in 2.1A03
FIX:
Apply SP3 to 2.1A when it is released. In the meantime, the following work around solved the problem (tested in 2.1A02):
Implement the following pseudo code in displayFields of viewercustom.p (or a super proc of one single affected viewer):
after RUN SUPER, do:
If pcColValues = ? /*no record to display*/ then do:
get allFieldHandles
Go through all these handles
if oneHandle:TYPE = "PROCEDURE"
/*known trick to detect if lookup, see issue 20031216-002 on Posse*/
then if {fnarg Signature 'initializeLookup':U h} NE ''
then do:
{get lookupHandle hWidgetHandle hField}. /*handle of the lookup's fill-in*/
/* If multiple fields in cLinkedField, then handle them in a loop... */
{get viewerLinkedWidgets cLinkedField hField}. /* name(s) of linked widget(s) */
/* In viewercustom.p 'hsdv' is TARGET-PROCEDURE, so no need to specify it */
hLinkedField = {fnarg widgetHandle cLinkedField hsdv}. /*now handle of linked widget*/
ASSIGN
hWidgetHandle:SCREEN-VALUE = ''
hLinkedField:SCREEN-VALUE = ''.
END.
end.
