if (yes) then undo, throw new Progress.Lang.AppError("Error1", 1). 
catch e as Progress.Lang.Error :
   define variable e1 as Progress.Lang.AppError no-undo.
   e1 = new Progress.Lang.AppError("Error2", 2).
   message "Caught!".
   undo, throw e1.
end catch.

In 4GL Caught! is displayed and Error2 is thrown.
In FWD Caught! is displayed and Error1 is thrown.

if (yes) then undo, throw new Progress.Lang.AppError("Error1", 1). 
catch e as Progress.Lang.Error :
   define variable e1 as Progress.Lang.AppError no-undo.
   e1 = new Progress.Lang.AppError("Error2", 2).
   message "Caught!".
   undo, throw e1.
   catch e2 as Progress.Lang.Error :
      message "Caught2!".
   end catch.
end catch.

In this situation, in FWD, none of the errors are being caught, Error1 is thrown and execution stops.

If undoThrowTopLevel is called inside a catch block, undoThrow is used instead for that error. undoThrow simply lacks any instructions for displaying the error, adding them results in displaying Error2, the problem is that Error1 is also displayed.

#7 Updated by Artur Școlnic almost 2 years ago

To match the behavior of 4GL for the test case in #9061-1, I disabled displayError in undoThrowTopLevel and added it in undoThrow, but I am not sure if this should be done at all, displaying the error shouldn't have a huge impact on the overall logic of the programs.
