ABC: Fix to lookup browse not placed correctly 1998-10-18 -- Geoff Bomford Newsgroups: TopSpeed.Products.C4.Bugs

This is a bug in the template. If you look at the code generated you will
see something like...( this is from the school app )
OF ?ENR:ClassNumber
! Start of "Control Event Handling"
! [Priority 6000]
IF QuickWindow{Prop:AcceptAll} = False
CLA:ClassNumber = ENR:ClassNumber
! Change .Fetch to .TryFetch
IF Access:Classes.TryFetch(CLA:KeyClassNumber) !GWB
ABWindow Was .Fetch(
IF SELF.Run(1,SelectRecord) = RequestCompleted
ENR:ClassNumber = CLA:ClassNumber
ELSE
SELECT(?ENR:ClassNumber)
CYCLE
END
END
END
ThisWindow.Reset(0)
The fetch method clears the record if no match is found, tryFetch does not
clear the record and so a match is found in the lookup procedure. The fix
needs to be made in the ABWindow.Clw file.
