Hello Peter,
This is a good question. The actual behavior you are encountering is because
the process will die after the execution of the code.
Thanks to the worker it is now possible to use a worker to display dialog with
the * parameter. A worker never die until you kill it with KILL WORKER.
This pattern will allow you to open a new dialog in a worker process called
“main_windows”.
C_BOOLEAN($1)
If (Count parameters=0)
CALL WORKER("main_windows";Current method name;True)
Else
$ref_win:=Open form window("myDialog";Plain form window)
DIALOG("myDialog";*)
End if
Hope it helps.
Best Regards,
Gabriel Inzirillo
