Hello

In PB2021 I'm getting this strange error when I open or close an object inherited from nonvisual:

---------------------------
PowerBuilder application execution error (R0021)
---------------------------
Application terminated.

Error: Bad runtime function reference at line 3 in create event of object pfc_n_base.
---------------------------
OK   
---------------------------

It starts happening randomly and the solution is a full rebuild of the target. It helps for next few hours and then it starts again. Sometimes it helps just open and close pfc_n_base. Pfc_n_base is just an empty object. I see nothing suspicious here. Therefore I thing pfc_n_base is just a victim. My guess is there's another broken object in my project which makes this message. Did you meet this strange behavior? Do you have an idea how to investigate it?

What I tried:

Rebuild

Optimise every library

Migrate all libraries

rebuild it again

 

Here's pfc_n_base code:

forward
global type pfc_n_base from nonvisualobject
end type
end forward

global type pfc_n_base from nonvisualobject
end type
global pfc_n_base pfc_n_base

type variables
Public:
constant integer 		SUCCESS = 1
constant integer 		FAILURE = -1
constant integer 		NO_ACTION = 0
constant integer 		CONTINUE_ACTION = 1
constant integer 		PREVENT_ACTION = 0

end variables

forward prototypes
protected function integer of_messagebox (string as_id, string as_title, string as_text, icon ae_icon, button ae_button, integer ai_default)
end prototypes

protected function integer of_messagebox (string as_id, string as_title, string as_text, icon ae_icon, button ae_button, integer ai_default);Return MessageBox(as_title, as_text, ae_icon, ae_button, ai_default)
end function

on pfc_n_base.create
call super::create
TriggerEvent( this, "constructor" )
end on

on pfc_n_base.destroy
TriggerEvent( this, "destructor" )
call super::destroy
end on
