I'm testing PB 2019 R2 #2203 vs. PB 2017 R3 #1880.

I create methods on application object and see below similarity + difference

Test Cases

  1. Create a function
    1. Open app object
    2. Create function with return statement
    3. Save app object
  2. Create an event
    1. Open app object
    2. Create event with return statement
    3. Save app object
// Test Case #1
public function integer of_test ();
return 0

// Test Case #2
event type integer ue_test();
return 0

 

Observations

PB Version Create Function Create Event
PB 2017 R3 #1880 Success Success
PB 2019 R2 #2203 Success Failure

The failure is that

  1. The user event disappears from the app object's event list when I save the app object.
  2. When I reopen app object in app painter I cannot find the event anywhere.
  3. When I reopen app object in Edit Source I see the event located at end of source code (misplaced compared to PB 2017 R3)
  4. Also in Edit Source I see no event header in the GLOBAL TYPE definition at top of script (missing compared to PB 2017 R3).

Can anyone repro this behavior?

Perhaps in an build of PB 2019 GA?

Thx /Michael

I agree. Just verified.

This is just one of those many small though important improvements to "core PowerBuilder".

THX!

I've done the test a bit different:

- did not define a function

- defined ue_test

- show up correctly in event list

- then define ue_test2

- now none of these events show in the list

 

By the way, I'm on 2019 R2 Beta (2203) for this test

This error can sometimes also happen in pb 12.6 or previous.

The workaround is to edit the sourcecode and manually add the functiont / event headers:

 

global type genapp from application
string appname = "genapp"
string themepath = "D:\Appeon2019\Shared\PowerBuilder\theme190"
string themename = "Do Not Use Themes"
boolean nativepdfvalid = false
boolean nativepdfincludecustomfont = false
long richtextedittype = 2
long richtexteditversion = 1
string richtexteditkey = ""
string appicon = ""
event type integer ue_test( )
event type integer ue_test2( )
end type
global genapp genapp

event type integer ue_test();return 0
end event

event type integer ue_test2();return 0
end event

 

The green text is what I've added. Now the events show up again in the list. As soon as you define new events or add or delete parameters it blows up again.

Ref Ken Guo's reply Appeon dev team has accepted this as bug so I hope for a fix.

I have seen "HELP, I lost my event script" appear seldom but still enough to scare - and this across I don't recall how many PB versions. Also across painters: Window, UserObject, Application, etc.

It feels like a sometimes uninitialized pointer (speaking good old pre-Windows MS-DOS programming) in 1+ M code lines of C++.

If Appeon manages to find root cause and fix it I will be really, really happy.

Oh yes, and then there's this other one that sometimes comes up "... bla bla bla ... is this manipulated exported code ... " or something similar and which is a real pain to solve.
