PowerBuilder 2019R3, b2703
Oracle 12C and PostgreSQL v12
IDE:     Windows 10 64 bit o/s
Runtime: Windows 19 server


Update:
   Perhaps the header portion of the Global Variables is fixed and gets overwritten at some schedule known only to PowerBuilder. I moved the declaration from it's current location into the Application object using EDIT and clicking on the Instance Variables tab, then the Global Variables option, then manually entering n_tr   sqlcz. Let's see if it sticks.

 

Summary:
   The new global value "n_tr   sqlcz" vanishes from the list of global variables after a full build or a compile. Why is this occurring and how can I set the app to retain the new global variable?

Details:
   1. I added a new n_tr value of sqlcz to the global variables using Edit Source. See image.
   2. I do a Full Build, and then a DEPLOY. Everything works.
   3. I do another full Build a day later and the variable sqlcz is no longer listed in the global
      variables; it appears to have been deleted by magic.

Hi Olan

That's quite a weird one. All I can think of is that the source is being reverted back somehow. I guess you are using some sort of sorce control, can you verify that the checked in source has the changes? Are you doing a getlatest and somehow overwriting the application object?

I fear that there is some external reason for what you are seeing.

All the best

David

Hi Olan;

  Yes, when you edited the raw App Object source code, you placed the n_tr sqlcz declaration in the wrong place (section).

Yep, that's what the IDE is for. ;-)

Ask "OKnight" who already added a global variable of type n_tr more than 15 years ago ;-)

(See comments in attached screenshot)

PowerBuilder destroys the line in the "forward" section when you edit and save the application object using the legal painter.
