O7 -> O$: hiding buttons when no current record

Hi $All,

I’m converting an Omnis 7 library to Omnis Studio, and I’ve come across a weird situation that I’m not sure how to fix.

In the O7 library, the properties of certain buttons were set so that the button wasn’t visible when a current record was loaded: “inactive when no record loaded”, and “do not gray”. When I converted it to O$, I noticed that the converter inserted some code into the $event on each button:

onEvDisabled
Do $cfield.$visible.$assign(kfalse) returns #F

onEvEnabled
Do $cfield.$visible.$assign(ktrue) returns #F

The problem is, the buttons are initially hidden, and when I load a record, they are not displayed.

(Status events are turned on for the fields in question)

I added some code to the $redraw for the window, but it seemed to be out of sync ie if I opened the window, the buttons were hidden. I clicked “Next” to load the next record, still no buttons. I clicked “Next” again and the buttons are displayed.

The window $event:

Begin Reversible Block
Set main file {DEBTORS}
End Reversible Block
Do $cwind.$objs.$sendall($ref.$enabled.$assign(kTrue))
Do default

I’m sure I’m missing something simple – it’s been a long time since I’ve done any O7 work!

Any input greatly appreciated!

Regards,
Paul.

A good example of quantum superposition is not only the classical 1930’s Schrodinger’s Cat experiments but on every BandAid has the phrase, “Sterile unless opened”.
