Hello everyone,

We are experiencing an issue where a function is being called twice unexpectedly. Our assumption is that this behavior might occur due to the button being pressed twice. However, this should be impossible, as PowerBuilder operates mostly synchronously.

 

We are specifically investigating whether either of the following scenarios could allow the button to become active again prematurely, enabling a second press during execution:

 

  • The use of the sleep() function during the wait time.
  • An HttpClient SendRequest operation.

 

Does anyone know if either of these could potentially cause this issue, or if there are other factors we might be overlooking?

Thanks you in advance,

Philippos
