I have a bit confused on the below scenario:-

1) I added this formula inside the Visible property of button:-

IsEmpty(
 Filter(
 'Printing Processes',
 'Booking Calendar ID' = varBKID
 )
)

the following formula inside the OnSelect:-

If(
 IsEmpty(
 Filter(
 'Printing Processes',
 'Booking Calendar ID' = varBKID
 )
 ),
 IfError(
 Patch(
 'Printing Processes',
 Defaults('Printing Processes'),
 {
 'Booking Calendar ID': varBKID,
 'Printing Status': {Value: "Draft"}
 }
 );
 ,
 Notify(
 "Can not create prinint order, please check you have the necessary permissions",
 NotificationType.Error
 ),
 Blank()
 ),
 Notify("There is already a Prinint Order created for this item",NotificationType.Error)
);

now when i submit the button >> it will be hidden.. so seems the formula inside the Visible property will be re-executed after clicking on the button..

but if i move the formula inside the Visible property of the button to be inside the screen onvisible property of the screen, as follow:-

UpdateContext({varISCurrentPrintProcessItemEmpty: IsEmpty(
 Filter(
 'Printing Processes',
 'Booking Calendar ID' = varBKID
 )
)})

and i added the local variable (varISCurrentPrintProcessItemEmpty) inside the button Visible property >> then when i click on the button it will not get hidden.. any advice? why the variable is not smart as the Visible property of the button?

Thanks
